مینیمالیسم یک سبک زندگی است که به افراد کمک می کند چیزهایی را که واقعاً به آنها نیاز دارند پیدا کنند و به زندگی آنها معنا ببخشد. ایده اصلی مینیمالیسم در واقع کمتر بودن نیست ، بلکه بیشتر بودن است. انتخاب مالکیت کمتر فقط شفافیت و تمرکز بر ارزشهایی است که می تواند چیزهایی را که واقعاً برای ما اهمیت دارند را برآورده کند. برند ال جی همیشه ارتباط قوی با شعار شرکت خود را تداعی می کند: "زندگی خوب است." در واقع ، تأکید اصلی این پیام بر اهمیت ایجاد رشد و تغییر برای بهبود سبک زندگی با ایجاد یک تجربه تجاری منحصر به فرد از طریق فناوری های نوآورانه است. برنامه مراقبت از مشتری مبتنی بر هوش مصنوعی LG ، که در لوازم خانگی پیشرو این شرکت استفاده می شود ، در مورد مصرف آب و انرژی به کاربران هشدار می دهد و توصیه های متفکرانه ای برای بهبود کارایی و صرفه جویی در هزینه ارائه می دهد. این یکی از نوآوری هایی است که شیوه زندگی ما را در این دهه بازتعریف می کند. به همین ترتیب ، برند برتر LG SIGNATURE دارای مجموعه ای مملو از محصولات مینیمالیستی است تا فضای اضافی را خالی کند. تلویزیون LG SIGNATURE OLED R نمونه کاملی از این امر است و با این فلسفه طراحی شده است که تلویزیون هنگام تماشا نباید فضای زیادی اشغال کند. زیرا ال جی معتقد است داشتن اقلام کمتر در محیط کوچکتر می تواند به طرز شگفت انگیزی آرامش بخش و بیشتر مطابق با سبک زندگی مینیمالیستی باشد. این شیوه زندگی می تواند رهایی بخش باشد ، اما نباید آن را با ساده زیستی اشتباه گرفت. عملکرد بیشتر با هزینه کمتر به حداکثر رساندن تجربه داخلی است. ال جی به جای اینکه به این امر به عنوان یک تهدید نگاه کند ، این روند را یک فرصت می داند.
LG Objet یک راه حل ایده آل برای طراحان مینیمالیستی است که به دنبال لوازم جانبی مناسب برای ایجاد فضای بیشتر در اتاق ها هستند. این محصولات کاملاً منحصر به فرد با اشکال تجربی خود فضاهای خصوصی را ارائه می دهند. هر دستگاه در این مجموعه به گونه ای ساخته شده است که از نظر زیبایی منحصر به فرد است ، فضای کمتری را اشغال می کند و راحتی بیشتری را به زندگی روزمره می افزاید. تلویزیون هایی که می توانند به صورت کشویی حرکت کنند و فضای پنهان قابل استفاده در پشت صفحه را فراهم می کنند و دستگاه های تصفیه هوا که می توانند تلفن های هوشمند را کنار تخت شارژ کرده و تجهیزات مورد نیاز را تهیه کنند. آنها در این گروه قرار می گیرند. LG Styler یک گزینه عالی برای علاقه مندان به خانه و مد است که به دنبال داشتن لباسشویی های حرفه ای بدون نیاز به اشغال یک اتاق کامل هستند. تنها کاری که باید انجام دهید این است که LG Styler پیشرفته را در کنار کمد لباس خود قرار دهید و از ویژگی های شگفت انگیز آن برای تهیه لباس بدون چین و چروک هیجان زده شوید. ال جی نشان داده است که به عنوان یک شرکت آینده نگر ، متعهد به ایجاد نوآوری های جدیدی است که سبک زندگی مشتریان را ساده و غنی می کند.

Jython Syntax, Statements, and Comments
This chapter describes Jython's syntax and statements. Jython has a simple, clean syntax that produces easy-to-read code, often considered the antithesis to the intricate appearances of Java, C, or Perl. Before addressing syntax, this chapter introduces Jython's interactive mode. This mode allows you to enter code one line at a time like common shell consoles, and it is the perfect venue for exploring Jython's syntax.
The Interactive ConsoleProgramming is often a succession of little puzzles. These little puzzles need to be worked out, tested, and confirmed before they can be added to the larger whole. That's where the interactive console comes in—you can explore code interactively, test things immediately, and experiment until the little puzzles are solved. The use of the interactive console, also called the interactive interpreter, is similar to shell programming, where you can enter commands interactively until they work, then place them in a file to make a shell script. The similarity fades when you realize that Jython itself is a very full and rich object-oriented programming language with a clean, easy-to-understand syntax. The interactive console is started by running jython without any parameters or by adding the -i command-line switch. After starting Jython you should see something that looks similar to this: Jython 2.0 on java1.2.2 (JIT: symcjit) Type "copyright", "credits" or "license" for more information. >>>_ The first line printed after starting Jython should include version information about Jython and Java as well as information about the JIT you are using. If you set the JAVA_COMPILER environment variable to NONE, Jython would confirm the change in JIT: Jython 2.0 on java1.2.2 (JIT: NONE) Type "copyright", "credits" or "license" for more information. >>> The > > > in the third line is the prompt for the interactive interpreter. At this prompt you can type Jython code that is evaluated as each line is entered. There is also a second prompt, which is three periods, .... This is used when statements span multiple physical lines. This testing, experimentation, and discovery within interactive mode is not limited to Jython. The interactive console is a powerful way of experimenting with and testing Java code. For this book, interactive mode is the primary means of learning Jython. Examples in the first part of this book are designed to be easy to experiment with, examine, and explore in interactive mode. The prompt symbols, > > > and . . ., are used to designate the use of the interactive interpreter throughout this book. Line Separators and Block Indentation SyntaxSimple Jython statements are contained in a logical line. What is a logical line? you might ask. Java and many other languages make this clear with punctuation. The semicolon is a line-separator in Java. A simple Java print would be System.out.println("Hello world"); Notice the semicolon. Now look at the comparable simple Jython print statement: print "Hello world" There are no semicolons to mark the end of the logical line. The semicolon has been a standard for terminating lines in many languages, but in Jython, a newline is sufficient to denote the boundary between logical lines—with but a few exceptions. If a Jython print statement were entered into the interactive interpreter, pressing the Enter key would cause the interpreter to execute the contents of that logical line. The same goes for a Jython file. Separate lines of Jython code in a file are interpreted as separate logical lines, unless they fit one of the exceptions that follow. There are cases in which the logical line for simple statements is not the same as the physical line. These cases are as follows:
SemicolonThe first case is the semicolon. This is the only case concerned with shortening the logical line. To place two or more logical lines on the same physical line, use the semicolon to separate statements. Even if there are not multiple statements on one line, the semicolon doesn't hurt anything. So, if Java programming habits lead to stray semicolons at the end of statements, no harm is done. Remember to be aware of code clarity when choosing this syntax to ensure that readability is not sacrificed for the sake of compactness. Listing 1.1 has multiple print statements on one physical line. The semicolon acts as the logical-line separator between these two print statements. The second statement, however, does not have a semicolon, because the newline character after it functions as the separator. Listing 1.1 Use of the Semicolon>>># it's tradition, what can I say >>>print "Hello "; print "world" Hello world Notice that the print statement automatically inserted a newline. This is part of the behavior of Jython's print statement. If this is not desired, you can append a comma after the print statement which pre-pends a space to the second print statement instead: >>>print "hello ",; print "world" hello world BackslashThe backslash (\) character is a line-continuation character. Multiple lines can be used to form one logical line with the \. An assignment is a simple Jython statement that binds a value to a variable, but what if you need to add so many values that they extended beyond the physical line? Listing 1.2 shows how the \ can be used to join multiple lines to do this. Listing 1.2 does not work interactively despite the legal syntax. To test Listing 1.2, place the code in a file (backslash.py used in example) and run it at the command line with jython backslash. py. Listing 1.2 Line Continuations with the Backslash# file: backslash.py var = 10 + 9 + 8 + 7 + 6 + \ 5 + 4 + 3 + 2 + 1 print var Results from running jython backslash.py at the command prompt: 55 Open GroupingsOpen groupings—meaning paired brackets [], braces {}, and parentheses ()— have their open (left) character on one line, and the closing character on a subsequent line. The logical line is extended until the closing half of these groupings appears. Listing 1.3 uses open groupings to spread a print statement over multiple physical lines. Listing 1.3 also does not work interactively despite being legal syntax (as of version 2.1a1). Listing 1.3 Using Parentheses to Span Multiple Lines# file: parens.py print ("this, " + "that, " + "the other thing.") Results from running jython parens.py: this, that, the other thing The indentations on the second and third lines of listing 1.3 are for appearances—this is unrelated to the continuation of the logical line. Indention matters in Jython, but in the case of joining lines with \ or open enclosures, the indentation of the continued lines do not matter. It's the indentation of the first line that does. Indention rules are addressed with compound statements later. Triple-Quotes In Jython, you have the option to use three matching quotes to mark the start and end of a string, matching either """ or '''. In a triple-quoted string, newlines and contained quotes are all preserved except for another triple-quote. Listing 1.4 shows a triple-quoted string spanning multiple lines. Note how it preserves internal quotes plus newline characters. Listing 1.4 is legal syntax, but also does not work interactively. Listing 1.4 Triple-Quoted Strings# file: triplequote.py print """This is a triple-quoted string. Newlines and quotation marks such as " and ' are preserved in the string.""" Results from running jython triplequote.py: This is a triple-quoted string. Newlines and quotation marks such as " and ' are preserved in the string. Code BlocksWith newline characters acting as the logical-line separators, it should be obvious that Jython already has much less punctuation than Java. What further reduces line noise is Jython's notation of code blocks in compound statements. These groupings, or "blocks" of code, are designated in Java by their enclosure in braces {}. Here lies an important distinction—Jython does not use braces to group statements but rather uses a combination of the : character and indention whitespace. Java's braces handle multiple levels of groupings with multiple enclosures of braces, or braces within braces { {} }. Jython instead uses multiple levels of indention—one indention for first grouping, two indentions for the second, and so on. Listing 1.5 uses Jython's if statement to show how compound statements use the : and indention to denote groupings of code. Listing 1.5 Indention-Based Groupings>>>if 1: ... print "Outer" ... if 1: ... print "Inner" ... print "Outer- again" ... Outer Inner Outer- again Notice how the execution of the compound statement happens only after the newline is entered at the leftmost margin in line six. This entry at the leftmost level notifies the interpreter that the indented grouping is completed and thus, the compound statement is completed.
CommentsLooking back at Listing 1.1 from earlier in this chapter, we see another important feature.The # sign. This designates a comment. All code between the # sign and the end of the physical line is ignored by the interpreter. Its appearance is not restricted to the beginning of a line; it can appear after a statement like this: print "Hello world" # It's tradition, what can I do The newline still terminates the logical line, but the space between # and the newline is treated as a comment and is ignored by the interpreter. Another way to comment code is with anonymous string literals. If you do not assign a string to a variable, it is anonymous, and does not affect the namespace in which it appears. This makes strings useful as comments, especially triple-quoted strings because they allow comments to span multiple lines. Listing 1.6 shows different comments. Listing 1.6 does not currently work in the interactive interpreter as noted earlier. Listing 1.6 Comments# file: comments.py # This is a comment "This works for a comment" """This comment can span multiple lines. Code that you do not want executed can go in triple quotes, and it is safe to use other quotation marks within the triple quotes, such as: print "hello" """ There is no output from running jython comments.py. Documentation StringsThe exploration and discovery mentioned when introducing interactive mode depends on introspection, the ability to look under the hood. An important Jython tool that helps when looking inside objects is Jython's self-documentation convention called doc strings. These are anonymous string literals appearing in function, method, and class definitions. Listing 1.7 defines a function called foo. The second line of this example is an anonymous string literal, and a doc string because of its location. Note that this string is one indention level in as it should be as part of foo's code block. This doc string uses the triple-quote notation, but that is not required. Any legal string quoting works; triple-quotes just make it easier in case the documentation grows to more than one line. Listing 1.7 Documentation Strings, __doc__>>> def foo(): ... """This is an example doc string""" ... pass ... >>> dir(foo) ['__dict__', '__doc__', '__name__', 'func_closure', 'func_code', 'func_defaults', 'func_doc', 'func_globals', 'func_name'] >>> foo.__doc__ 'This is an example doc string' >>> The function dir() is a built-in function that looks at name bindings within a namespace. Listing 1.7 uses dir to look at function foo, and returns a list of names defined inside foo. In this list it is __doc__. Looking at the contents of foo.__doc__ show that it is the name bound to the doc string provided in the function definition. The actual results of calling dir(foo) differs between Jython 2.0 and Jython 2.1a1 (the current version as of this writing). Do not be concerned if your output differs slightly. StatementsThis section includes definitions and usage examples of Jython statements. Statements are categorized into simple statements, those with a single clause, and compound statements, those with multiple clauses or an associated code block. Simple StatementsSimple statements are those Jython statements with a single clause, encompassing one logical line. These statements are often confused with built-in functions; however, there is a distinction. Statements are part of the syntax as opposed to functions or data objects defined within a namespace. The following sections list Jython's simple statements and their syntax, and provides an example usage. assertThe assert statement tests whether an expression is true and raises an exception if it is not true. If two expressions are supplied, the second expression will be used as the argument to the raised AssertException. Setting __debug__=0, and possibly the -O command-line switch in future releases, disables asserts. Syntax: "assert" expression [, expression] Example: >>>a=21 >>>assert a", line 1, in ? AssertionError: assignmentAn assignment binds an object to an identifier. Jython has simple assignment (=) and augmented assignments ( + =, -=, *=, /=, * * =, %=, < < =, > > =, &=, |=, ^=). Syntax: variable assignment-operator value Example: >>>var=3 >>>print var 3 >>>var += 2 >>>print var 5 breakThe break statement terminates execution of an enclosing loop and continues execution after the loop block. This means it does skip the else block if it exists. Syntax: break Example: >>>for x in (1,2,3,4): ... if x==3: ... break ... print x ... 1 2 >>> continueThe continue statement halts execution of the current loop block and start the enclosing loop again at its next iteration. Syntax: continue Example: >>>for x in (1,2,3,4): ... if x==3: ... continue ... print x ... 1 2 4 >>> delThe del statement removes a variable.The variable can be one within the namespace or a specific list or dictionary value. Syntax: "del" identifier Example: >>>a="foo" >>>print a foo >>>del a >>>print a Traceback (innermost last): File "", line 1, in ? NameError: a>>> >>> a = [1,2,3] >>> del a[1] >>> print a [1, 3] execThe exec statement executes Jython code. The exec statement requires an expression, which represents the code it needs to execute. A string, open file object, or code object can be supplied for this expression, which is the first parameter to exec(). If two parameters are provided, the second is used as the global dictionaries in which the code is executed. If three parameters are provided, the first is a dictionary used as the global namespace, and the second is the local namespace in which the code is executed. Syntax: "exec" expression ["in" expression ["," expression]] Example: >>>exec "print 'The exec method is used to print this'" The exec method is used to print this >>> globalThe global statement tells the parser to use global name bindings for listed identifiers throughout the current code block. Why? Because an assignment in a local code block identifies all references to that assigned variable as local. It's easier to see in the comparison of the following two code snippets: >>>var = 10 >>>def test(): ... print var # try and print the global identifier 'var' ... >>>test() 10 >>> We see that var is found and prints. So far, so good. Now, what happens if we assign something to var after the print statement? >>>var = 10 >>>def test(): ... print var # try and print the global identifier 'var' ... var = 20 # assign to 'var' in local namespace ... >>>test() Traceback (innermost last): File "", line 1, in ? File "", line 2, in test NameError: local: 'var' >>> The identifier var is designated as local because of the assignment within the code block, so the print statement is an error because var does not exist yet in the local namespace. This is the reason for global. Syntax: global identifier ["," identifier]* Example: >>>var = 10 >>>def test(): ... global var # must designate var global first. ... print var # try and print the global identifier 'var' ... var = 20 # assign to 'var' in local namespace ... >>>test() 10 >>>print var # check global 'var' 20 >>> importThe import statement locates and initializes what is imported and binds it to variables in the scope that import was called in. You can optionally change the name of the variables imports are bound to with an as new-name suffix to the import statement. Syntax: import module-name OR from module-name import names OR import module-name as new-name OR from module-name import name as new-name Example: >>>import sys >>>from java import util >>>import os as myOS >>>from sys import packageManager as pm passThe "do nothing" statement. This statement is a placeholder. Syntax: pass Example: >>>for x in (1,2,3,4): ... pass ... >>> The print statement evaluates an expression, converts the result to a string if needed, and writes the string to sys.stdout or whatever file-like object it is directed to with the >> syntax. A file-like object is one with a write method defined. Syntax: print [expression] OR print >> fileLikeObject, [expression] Example: >>>print "Hello world" Hello world raiseThe raise statement evaluates any expressions provided with it and raises an exception accordingly. Syntax: raise [expression [, expression [, traceback]]] Example: >>>raise ValueError, "No value provided" Traceback (innermost last): File "", line 1, in ? ValueError: No value provided returnThe return statement ends execution of the method or function it is called in after evaluating any provided expression for use as a return value. If no expression is provided, the value None is returned. Syntax: return [expression] Example: >>>def someFunction(): ... return "This string is the return value" Compound StatementsCompound statements are those statements that have a grouping or "block" of code associated with them. Flow control statements such as if, for, and while are compound statements. These are difficult to introduce without mentioning Jython's block indentation syntax. A code block, or grouping of statements, in Java is contained in braces {}. Multiple levels of groupings are in nested braces { {} }. This is not so for Jython. Rather, Jython uses the colon, :, and indentation to identify blocks of code. With this knowledge, we can define Jython's compound statements. The following sections explain Jython's compound statements and their definitions. classThe class statement is used to define a class. Evaluation of a class statement defines a class in that current scope. Calling a class calls its constructor if defined and returns an instance of that class. Syntax: "class" name[(base-class-name)]: Example: >>>class test: # no base class ... pass # place holder ... >>>t = test() # Calls class statement to make an instance defThe def statement is how functions and methods are defined. Syntax: "def" name([parameters]): statements Example: >>>def hello(person): ... print "Hello ", person ... >>>hello("world") # calls the hello function Hello world forThe for statement is a flow-control statement that iterates through a loop once for each member of a sequence. The for statement can also include an optional else clause that is executed after the sequence has expired. Syntax: "for" variable "in" expression":" statements ["else:"] statements The expression provided must evaluate to a list. Example: >>>for x in (1,2,3): ... print x, ...else: ... print "in else clause" ... 1 2 3 in else clause >>> ifThe if statement executes a block of code conditionally when an expression evaluates to true. Syntax: if expression: statements elif expression: statements else: statements If the first expression evaluates to false, the interpreter proceeds to evaluate the elif expression if provided. If all elif conditions are false, the else group of statements is executed. Example: >>>if a==b: ... print "variable a equals variable b" ...elif a>b: ... print "variable a is greater than b" ...else: ... print "variable a is less than b" tryThe try statement executes a block of code until completion or until an error. Syntax: "try:" statements "except" ["," expression ["," variable]]":" statements ["else:" statements] OR ["finally:" statements] Only one of the else or finally clause can be used, not both. If the try block of code runs without error, it proceeds to execute the block of code in its finally block. If the try block has an error, it stops execution of that block and proceeds to the except clause. Example: >>>try: ... 1/0 ...except ZeroDivisionError, e: ... print "You cannot divide by zero: ", e ... You cannot divide by zero: integer division or modulo >>> whileThe while statement executes a block of code as long as a provided expression evaluates to true. Syntax: "while" expression ":" Example: >>>x = 10 >>>while x>0: ... print x, ... x -= 1 ... 10 9 8 7 6 5 4 3 2 1 Comparing Jython and JavaTable 1.1 lists the statements used in Jython and compares them with Java's implementation.

چه افرادی برنامه نویسی پایتون را یاد نگیرند؟پایتون راهی سریع و ساده برای توسعه و پیش بردن مهارتهای جدید است که میتواند شما را از یک برنامه نویس صفر کیلومتر به یک حرفه ای تبدیل کند و قطعاً تأثیر مثبتی بر شغل تان میگذارد. پایتون خیلی ساده است و هر فردی را حتی با سطح صفر در برنامه نویسی میتواند به سادگی و با کمک سینتکس قابل درکاش که شبیه به زبان انگلیسی است آموزش دهد و به یک برنامه نویس تبدیل کند. به علاوه اینکه پایتون یک محیط کد نویسی تعاملی دارد که باعث میشود کار با این زبان و تست کردن اجرای اسکریپتها در حین یادگیری ساده شود.
1- افرادی که قصد دارند توسعه دهنده وب باشند
تواناییهای پایتون خیلی گستردهتر از توسعه وب است. اینستاگرام بزرگترین سایتی است که Django (یک فریم ورک وب پایتون) را اجرا میکند. یکی از مهندسان ارشد اینستاگرام به نام ژیون لی در این باره میگوید: «ما استفاده از پایتون را به این دلیل آغاز کردیم زیرا کار با آن راحت است، اما ما طی سالها تغییرات زیادی روی آن انجام دادیم تا آن را تا حدی که مورد انتظار ما است ساده نگه داریم.» این نشان دهنده آن است که Django یک فریم ورک قدرتمند و با ظرافت است. اما پرسش اینجا است که وقتی جاوا اسکریپت از قبل برای چنین منظوری در نظر گرفته شده است چرا باید Django را یاد گرفت؟ فریم ورکهای جاوا اسکریپت مثل React و Vue.js بسیار پرطرفدار هستند. هر دو میتوانند از Django و سایر فریم ورکهای سمت سرور مثل Ruby on Rails استفاده کنند. اما از آنجا که هر دو زبانهای مبتنی بر جاوا اسکریپت هستند، چرا شما باید از چیزی غیر از Node.js استفاده کنید؟ این به معنای آن نیست که جاوا اسکریپت یک زبان برنامه نویسی کامل و ایدهال است. برعکس بسیاری به خلاف این اعتقاد دارند. اما اگر شما تازه توسعه وب را آغاز کردهاید، هنوز بهترین انتخاب برای شما همان جاوا اسکریپت است.

years. The main objective in Protecting Your Wealth in Good Times and Bad is to reach a point in life when you work only if you want to and, if you stop working, when you do not fear outliving your money.
Retirees are living longer and healthier, traveling more, enjoy better housing, better automobiles, better communications, and generally spending more money than prior generations. As life expectancy extends and lifestyles rise, future retirees will need more income and will rely more on their personal savings for that income than past generations. Traditional sources of retirement income— Social Security and employer pension plans—are on the decline. As a result, the nest egg people accumulate during their working years will dictate their quality of life in retirement. That is why it is impor- tant for you to protect your wealth from simple, yet costly mistakes. Every penny counts. Through proper planning, prudence, and perse- verance, you can accumulate the wealth you need to enjoy your Golden Years.
The State of Retirement Savings
A secure retirement means having enough sources of income to maintain your standard of living after a regular paycheck stops. Unfortunately, traditional sources of retirement income from an employer pension and Social Security have diminished and will con- tinue to fall in the future. At the same time the cost of retirement will continue to rise. This will be a dilemma for many people. Neither employers nor the government are as generous as they used to be. Most employers are cutting back benefits for retirees. The Social Security system will not survive in its current form when 50 million baby boomers retire over the next 25 years.
Several large companies have already dropped employer-funded defined benefit pension plans (DB plans) in favor of employee- funded 401(k) and other types of defined contribution plans (DC plans). (See Figure 1-1 for details.) By shifting the responsibility for retirement savings to an employee-funded plan, employers can save a significant amount of money and reduce their incredibly large reg- ulatory burden. Several large employers continue to fund retirement plans, but have shifted to the more liberal cash balance plans, in

which retirement benefits vary with market conditions and there is no liability on the employer to make up the difference. In addition to changes at large firms, hundreds of thousands of small business- es offer no retirement plan at all to their employees. Consequently, millions of workers must set up their own individual retirement accounts and fund them on a regular basis.
The reduction in the number of employer-funded DB plans is occurring for several reasons. First, since a DB plan guarantees monthly retirement checks for all eligible employees and since the rate of return on the investments in a pension account is uncertain, the plan can become very expensive to the company in the years ahead if there is not enough money in the fund to pay benefits. Second, DB plans are expensive to administer and maintain. The record-keeping cost and regulatory burden increase as the plan grows. Third, DB plans do not work well for employees in today’s dynamic business environment, where people shift jobs and careers more frequently than in the past.
Due to legal uncertainties and escalating costs, several compa- nies have converted defined benefit plans into cash balance plans. A cash balance plan is a hybrid of a defined benefit and a defined con- tribution plan (such as a 401(k) plan). Like DB plans, employers
