Notes on this release:

• The binaries for AMD64 will also work on processors that implement the Intel 64 architecture. (Also known as the «x64» architecture, and formerly known as both «EM64T» and «x86-64».) They will not work on Intel Itanium Processors (formerly «IA-64»).
• There is important information about IDLE, Tkinter, and Tcl/Tk on Mac OS X here.

This is the seventh maintenance release of Python 3.8

Note: The release you’re looking at is Python 3.8.7, a bugfix release for the legacy 3.8 series. Python 3.9 is now the latest feature release series of Python 3. Get the latest release of 3.9.x here.

macOS 11 Big Sur not fully supported

Python 3.8.7 is not yet fully supported on macOS 11 Big Sur. It will install on macOS 11 Big Sur and will run on Apple Silicon Macs using Rosetta 2 translation. However, a few features do not work correctly, most noticeably those involving searching for system libraries (vs user libraries) such as ctypes.util.find_library() and in Distutils. This limitation affects both Apple Silicon and Intel processors. We are looking into improving the situation for Python 3.8.8.

Major new features of the 3.8 series, compared to 3.7

• PEP 572, Assignment expressions
• PEP 570, Positional-only arguments
• PEP 587, Python Initialization Configuration (improved embedding)
• PEP 590, Vectorcall: a fast calling protocol for CPython
• PEP 578, Runtime audit hooks
• PEP 574, Pickle protocol 5 with out-of-band data
• Typing-related: PEP 591 (Final qualifier), PEP 586 (Literal types), and PEP 589 (TypedDict)
• Parallel filesystem cache for compiled bytecode
• Debug builds share ABI as release builds
• f-strings support a handy = specifier for debugging
• continue is now legal in finally: blocks
• on Windows, the default asyncio event loop is now ProactorEventLoop
• on macOS, the spawn start method is now used by default in multiprocessing
• multiprocessing can now use shared memory segments to avoid pickling costs between processes
• typed_ast is merged back to CPython
• LOAD_GLOBAL is now 40% faster
• pickle now uses Protocol 4 by default, improving performance

There are many other interesting changes, please consult the «What’s New» page in the documentation for a full list.

Windows users

• The binaries for AMD64 will also work on processors that implement the Intel 64 architecture. (Also known as the «x64» architecture, and formerly known as both «EM64T» and «x86-64».)
• There are now «web-based» installers for Windows platforms; the installer will download the needed software components at installation time.
• There are redistributable zip files containing the Windows builds, making it easy to redistribute Python as part of another software package. Please see the documentation regarding Embedded Distribution for more information.

macOS users

• For Python 3.8, we provide one installer: 64-bit-only that works on macOS 10.9 (Mavericks) and later systems.
• Please read the «Important Information» displayed during installation for information about SSL/TLS certificate validation and the running the «Install Certificates.command».

And now for something completely different

(Cut to BBC world symbol.)
Continuity Voice: (Eric Idle) Now on BBC television a choice of viewing. On BBC 2 — a discussion on censorship between Derek Hart, The Bishop of Woolwich, and a nude man. And on BBC 1 — me telling you this. And now.
(Sound of TV set bring switched off. The picture reduces to a spot and we see it was actually on a TV set which has just been switched off by the housewife. The inspector holds a cup with a cherry on a stick in it.)
She: (Terry Jones) We don’t want that, do we. Do you really want that cherry in your tea? Do you like doing this job?
Inspector: (Michael Palin) Well, it’s a living, isn’t it?

Release Date: July 8, 2019

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.

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.
