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:

  • Steve Dower (Windows binaries) (key id: FC62 4643 4870 34E5)
  • Łukasz Langa (3.8.x source files and tags) (key id: B269 95E3 1025 0568)
  • Ned Deily (macOS binaries, 3.7.x / 3.6.x source files and tags) (key ids: 2D34 7EA6 AA65 421D, FB99 2128 6F5E 1540, and Apple Developer ID DJ3H93M7VJ)
  • Larry Hastings (3.5.x source files and tags) (key id: 3A5C A953 F73C 700D)
  • Benjamin Peterson (2.7.z source files and tags) (key id: 04C3 67C2 18AD D4FF and A4135B38)

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.

  • (These instructions are geared to GnuPG and Unix command-line users.)

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.

Latest version

Last released:

A simple framework for building complex web applications.

Project description

Flask is a lightweight WSGI web application framework. It is designedto make getting started quick and easy, with the ability to scale up tocomplex applications. It began as a simple wrapper around Werkzeugand Jinja and has become one of the most popular Python webapplication frameworks.

Flask offers suggestions, but doesn鈥檛 enforce any dependencies orproject layout. It is up to the developer to choose the tools andlibraries they want to use. There are many extensions provided by thecommunity that make adding new functionality easy.
