The core of extensible programming is defining functions. Python allows mandatory and optional arguments, keyword arguments, and even arbitrary argument lists. More about defining functions in Python 3
Lists (known as arrays in other languages) are one of the compound data types that Python understands. Lists can be indexed, sliced and manipulated with other built-in functions. More about lists in Python 3
Calculations are simple with Python, and expression syntax is straightforward: the operators + , — , * and / work as expected; parentheses () can be used for grouping. More about simple math functions in Python 3.
Experienced programmers in any other language can pick up Python very quickly, and beginners find the clean syntax and indentation structure easy to learn. Whet your appetite with our Python 3 overview.
Python knows the usual control flow statements that other languages speak — if , for , while and range — with some of its own twists, of course. More control flow tools in Python 3
Python is a programming language that lets you work quickly and integrate systems more effectively. Learn More

Python
Python – один из распространенных языков программирования, стал популярным благодаря упрощенному синтаксису и большому количеству полезных функций.
Скачать программу для программирования Python 3 можно бесплатно на русском языке для Windows 7, 8, 10 по ссылкам ниже с официального сайта.
Создатели Python особо выделяют производительность и читаемость кода. К наиболее запоминающимся чертам языка можно отнести — динамическую типизацию, возможность автоматически управлять памятью, встроенный механизм для обработки исключений, поддержку многопоточных вычислений и высокоуровневую структуризацию данных.
Главные преимущества Python:
- Чистый понятный синтаксис кода.
- Утилита осуществляет хороший самоанализ.
- Код отображается отчётливо и ваши глаза не будут быстро уставать при работе с ним.
- Возможность создавать модули и пакеты.
- Обрабатывает ошибки в виде исключений.
- Поддерживает динамические типы данных.
- Вы всегда сможете воспользоваться библиотекой, которая содержит очень много данных.
- Дополнения и модули можно легко написать на других распространённых языках программирования.
Python поддерживает все самые популярные и необходимые парадигмы и доступен на русском языке. Код в программе может организовываться в функции и классы, а затем объединяться в модули (которые уже потом могут быть объединены в так называемые пакеты).

Sponsors
Visionary sponsors like Google help to host Python downloads.
Licenses
All Python releases are Open Source. Historically, most, but not all, Python releases have also been GPL-compatible. The Licenses page details GPL-compatibility and Terms and Conditions.
Sources
For most Unix systems, you must download and compile the source code. The same source code archive can also be used to build the Windows and Mac versions, and is the starting point for ports to all other platforms.
Download the latest Python 3 and Python 2 source.
Alternative Implementations
This site hosts the «traditional» implementation of Python (nicknamed CPython). A number of alternative implementations are available as well.
History
Python was created in the early 1990s by Guido van Rossum at Stichting Mathematisch Centrum in the Netherlands as a successor of a language called ABC. Guido remains Python’s principal author, although it includes many contributions from others.
Release Schedules
Information about specific ports, and developer info
OpenPGP Public Keys
Source and binary executables are signed by the release manager or binary builder using their OpenPGP key. Release files for currently supported releases are signed by the following:
Release files for older releases which have now reached end-of-life may have been signed by one of the following:
- Anthony Baxter (key id: 0EDD C5F2 6A45 C816)
- Georg Brandl (key id: 0A5B 1018 3658 0288)
- Martin v. Löwis (key id: 6AF0 53F0 7D9D C8D2)
- Ronald Oussoren (key id: C9BE 28DE E6DF 025C)
- Barry Warsaw (key ids: 126E B563 A74B 06BF, D986 6941 EA5B BD71, and ED9D77D5)
You can import a person’s public keys from a public keyserver network server you trust by running a command like:
or, in many cases, public keys can also be found at keybase.io. On the version-specific download pages, you should see a link to both the downloadable file and a detached signature file. To verify the authenticity of the download, grab both files and then run this command:
Note that you must use the name of the signature file, and you should use the one that’s appropriate to the download you’re verifying.

Other Useful Items
- Looking for 3rd party Python modules? The Package Index has many of them.
- You can view the standard documentation online, or you can download it in HTML, PostScript, PDF and other formats. See the main Documentation page.
- Information on tools for unpacking archive files provided on python.org is available.
- Tip: even if you download a ready-made binary for your platform, it makes sense to also download the source. This lets you browse the standard library (the subdirectory Lib) and the standard collections of demos (Demo) and tools (Tools) that come with it. There’s a lot you can learn from the source!
- There is also a collection of Emacs packages that the Emacsing Pythoneer might find useful. This includes major modes for editing Python, C, C++, Java, etc., Python debugger interfaces and more. Most packages are compatible with Emacs and XEmacs.
