Python is a widely usedhigh level programming language for general purpose programming, created by Guido van Rossum and first released in 1. An interpreted language, Python has a design philosophy that emphasizes code readability notably using whitespace indentation to delimit code blocks rather than curly brackets or keywords, and a syntax that allows programmers to express concepts in fewer lines of code than might be used in languages such as C or Java. 2. It provides constructs that enable clear programming on both small and large scales. 2.

Python features a dynamic type system and automatic memory management. It supports multiple programming paradigms, including object oriented, imperative, functional and procedural, and has a large and comprehensive standard library. 2.

His continuing central role in Pythons development is reflected in the title given him by the Python community Benevolent Dictator For Life BDFL. On the origins of Python, Van Rossum wrote in 1. In December 1. 98. I was looking for a hobby programming project that would keep me occupied during the week around Christmas. My office. would be closed, but I had a home computer, and not much else on my hands. I decided to write an interpreter for the new scripting language I had been thinking about lately a descendant of ABC that would appeal to UnixChackers. I chose Python as a working title for the project, being in a slightly irreverent mood and a big fan of Monty Pythons Flying Circus. Python 2. October 2. 00. 0 and had many major new features, including a cycle detectinggarbage collector and support for Unicode. With this release, the development process became more transparent and community backed. 3. Python 3. 0 initially called Python 3. December 2. 00. 8 after a long testing period. It is a major revision of the language that is not backward compatible with previous versions. 3. However, many of its major features have been backported to the backward compatible Python 2. Python 2. 7s end of life date a. EOL, sunset date was initially set at 2. Python 3. 3. 53. In January 2. 01. Google announced work on a Python 2. Gotranscompiler. The Register speculated that this was in response to Python 2. Google cited performance under concurrent workloads as their only motivation. 3. Features and philosophyeditPython is a multi paradigm programming language. Object oriented programming and structured programming are fully supported, and many of its features support functional programming and aspect oriented programming including by metaprogramming3. Many other paradigms are supported via extensions, including design by contract4. Python uses dynamic typing, and a combination of reference counting and a cycle detecting garbage collector for memory management. It also features dynamic name resolution late binding, which binds method and variable names during program execution. Pythons design offers some support for functional programming in the Lisp tradition. It has filter, map, and reduce functions list comprehensions, dictionaries, and sets and generator expressions. 4. The standard library has two modules itertools and functools that implement functional tools borrowed from Haskell and Standard ML. 4. The languages core philosophy is summarized in the document The Zen of Python PEP 2. Beautiful is better than ugly. Explicit is better than implicit. Simple is better than complex. Complex is better than complicated. Readability counts. Rather than having all of its functionality built into its core, Python was designed to be highly extensible. This compact modularity has made it particularly popular as a means of adding programmable interfaces to existing applications. Van Rossums vision of a small core language with a large standard library and easily extensible interpreter stemmed from his frustrations with ABC, which espoused the opposite approach. 2. While offering choice in coding methodology, the Python philosophy rejects exuberant syntax such as that of Perl in favor of a simpler, less cluttered grammar. As Alex Martelli put it To describe something as clever is not considered a compliment in the Python culture. 4. Pythons philosophy rejects the Perl there is more than one way to do it approach to language design in favor of there should be oneand preferably only oneobvious way to do it. 4. Pythons developers strive to avoid premature optimization, and reject patches to non critical parts of CPython that would offer marginal increases in speed at the cost of clarity. 4. When speed is important, a Python programmer can move time critical functions to extension modules written in languages such as C, or use Py. Py, a just in time compiler. Cython is also available, which translates a Python script into C and makes direct C level API calls into the Python interpreter. An important goal of Pythons developers is keeping it fun to use. This is reflected in the languages namea tribute to the British comedy group Monty Python4. Monty Python sketch instead of the standard foo and bar. 5. A common neologism in the Python community is pythonic, which can have a wide range of meanings related to program style. To say that code is pythonic is to say that it uses Python idioms well, that it is natural or shows fluency in the language, that it conforms with Pythons minimalist philosophy and emphasis on readability. In contrast, code that is difficult to understand or reads like a rough transcription from another programming language is called unpythonic. Users and admirers of Python, especially those considered knowledgeable or experienced, are often referred to as Pythonists, Pythonistas, and Pythoneers. 5. Syntax and semanticseditPython is meant to be an easily readable language. Its formatting is visually uncluttered, and it often uses English keywords where other languages use punctuation. Unlike many other languages, it does not use curly brackets to delimit blocks, and semicolons after statements are optional. It has fewer syntactic exceptions and special cases than C or Pascal. 5. IndentationeditPython uses whitespace indentation, rather than curly braces or keywords, to delimit blocks. Linguaggio di programmazione Python.
