Other just-in-time Python compilers have been developed, but are now unsupported: In 2005, Nokia released a Python interpreter for the Series 60 mobile phones named PyS60. SageMath is a mathematical software with a notebook interface programmable in Python: its library covers many aspects of mathematics, including algebra, combinatorics, numerical mathematics, number theory, and calculus. Libraries such as NumPy, SciPy and Matplotlib allow the effective use of Python in scientific computing,[157][158] with specialized libraries such as Biopython and Astropy providing domain-specific functionality. Python is a computer programming language that lets you work more quickly than other programming languages. The mailing list python-dev is the primary forum for the language's development. Since 2003, Python has consistently ranked in the top ten most popular programming languages in the TIOBE Programming Community Index where, as of February 2020[update], it is the third most popular language (behind Java, and C). From Python 2.5, it is possible to pass information back into a generator function, and from Python 3.3, the information can be passed through multiple stack levels.[75]. Some parts of the standard library are covered by specifications (for example, the Web Server Gateway Interface (WSGI) implementation wsgiref follows PEP 333[106]), but most modules are not. Python knows the usual control flow statements that other languages speak — if, for, while and range — with some of its own twists, of course. The second part of the version number is incremented. [8] Its implementation began in December 1989. Our relaunched community-run job board is the place to go. For example: Statements cannot be a part of an expression, so list and other comprehensions or lambda expressions, all being expressions, cannot contain statements. An experimental optional static type checker named mypy supports compile-time type checking.[89]. As of November 2019,[update] the Python Package Index (PyPI), the official repository for third-party Python software, contains over 200,000[107] packages with a wide range of functionality, including: Most Python implementations (including CPython) include a read–eval–print loop (REPL), permitting them to function as a command line interpreter for which the user enters statements sequentially and receives results immediately. What is Python programming language used for? Looking for work or have a Python related position that you're trying to hire for? In contrast to Perl's "there is more than one way to do it" motto, Python embraces a "there should be one—and preferably only one—obvious way to do it" design philosophy. [66][67], Python is meant to be an easily readable language. Tuples and Sequences — Python 3.7.1rc2 documentation", "PEP 498 -- Literal String Interpolation", "Why must 'self' be used explicitly in method definitions and calls? Major or "feature" releases, about every 18 months, are largely compatible but introduce new features. [115][116], Stackless Python is a significant fork of CPython that implements microthreads; it does not use the C memory stack, thus allowing massively concurrent programs. Some Python expressions are similar to languages such as C and Java, while some are not: In Python, a distinction between expressions and statements is rigidly enforced, in contrast to languages such as Common Lisp, Scheme, or Ruby. Twisted is a framework to program communications between computers, and is used (for example) by Dropbox. [166], Python is commonly used in artificial intelligence projects and machine learning projects with the help of libraries like TensorFlow, Keras, Pytorch and Scikit-learn. Python being a great general purpose and high level language, can be used to create Desktop GUI applications, web applications and web frameworks. [62] When speed is important, a Python programmer can move time-critical functions to extension modules written in languages such as C, or use PyPy, a just-in-time compiler. [94], Rounding towards negative infinity, though different from most languages, adds consistency. / before version 3.0 is classic division. Python's design offers some support for functional programming in the Lisp tradition. 5**3 == 125 and 9**0.5 == 3.0, and a matrix multiply operator @ . [114] Its just-in-time compiler brings a significant speed improvement over CPython but several libraries written in C cannot be used with it. Old-style classes were eliminated in Python 3.0. For Internet-facing applications, many standard formats and protocols such as MIME and HTTP are supported. Object-oriented programming and structured programming are fully supported, and many of its features support functional programming and aspect-oriented programming (including by metaprogramming and metaobjects (magic methods)). Python's design and philosophy have influenced many other programming languages: Python's development practices have also been emulated by other languages.
