All rights reserved. Python 3.x is a new version of the language, which is incompatible with the 2.x line of releases. The language is mostly the same, but many details, especially how built-in objects like dictionaries and strings work, have changed considerably, and a lot of deprecated features have finally been removed. Using Python ------------ Installable Python kits, and information about using Python, are available at `python.org`_. .. _python.org: https://www.python.org/ Build Instructions ------------------ On Unix, Linux, BSD, OSX, and Cygwin: ./configure make make test sudo make install This will install Python as python3. You can pass many options to the configure script; run "./configure --help" to find out more. On OSX and Cygwin, the executable is called python.exe; elsewhere it's just python. On Mac OS X, if you have configured Python with --enable-framework, you should use "make frameworkinstall" to do the installation. Note that this installs the Python executable in a place that is not normally on your PATH, you may want to set up a symlink in /usr/local/bin. On Windows, see PCbuild/readme.txt. If you wish, you can create a subdirectory and invoke configure from there. For example: mkdir debug cd debug ../configure --with-pydebug make make test (This will fail if you *also* built at the top-level directory. You should do a "make clean" at the toplevel first.) To get an optimized build of Python, "configure --enable-optimizations" before you run make. This sets the default make targets up to enable Profile Guided Optimization (PGO) and may be used to auto-enable Link Time Optimization (LTO) on some platforms. For more details, see the sections bellow. Profile Guided Optimization --------------------------- PGO takes advantage of recent versions of the GCC or Clang compilers. If ran, "make profile-opt" will do several steps. First, the entire Python directory is cleaned of temporary files that may have resulted in a previous compilation. Then, an instrumented version of the interpreter is built, using suitable compiler flags for each flavour. Note that this is just an intermediary step and the binary resulted after this step is not good for real life workloads, as it has profiling instructions embedded inside. After this instrumented version of the interpreter is built, the Makefile will automatically run a training workload. This is necessary in order to profile the interpreter execution. Note also that any output, both stdout and stderr, that may appear at this step is suppressed. Finally, the last step is to rebuild the interpreter, using the information collected in the previous one. The end result will be a Python binary that is optimized and suitable for distribution or production installation. Link Time Optimization ---------------------- Enabled via configure's --with-lto flag. LTO takes advantages of recent compiler toolchains ability to optimize across the otherwise arbitrary .o file boundary when building final executables or shared libraries for additional performance gains. What's New ---------- We have a comprehensive overview of the changes in the "What's New in Python 3.5" document, found at http://docs.python.org/3.5/whatsnew/3.5.html For a more detailed change log, read Misc/NEWS (though this file, too, is incomplete, and also doesn't list anything merged in from the 2.7 release under development). If you want to install multiple versions of Python see the section below entitled "Installing multiple versions". Documentation ------------- Documentation for Python 3.5 is online, updated daily: http://docs.python.org/3.5/ It can also be downloaded in many formats for faster access. The documentation is downloadable in HTML, PDF, and reStructuredText formats; the latter version is primarily for documentation authors, translators, and people with special formatting requirements. If you would like to contribute to the development of Python, relevant documentation is available at: http://docs.python.org/devguide/ For information about building Python's documentation, refer to Doc/README.txt. Converting From Python 2.x to 3.x --------------------------------- Python starting with 2.6 contains features to help locating code that needs to be changed, such as optional warnings when deprecated features are used, and backported versions of certain key Python 3.x features. A source-to-source translation tool, "2to3", can take care of the mundane task of converting large amounts of source code. It is not a complete solution but is complemented by the deprecation warnings in 2.6. See http://docs.python.org/3.5/library/2to3.html for more information. Testing ------- To test the interpreter, type "make test" in the top-level directory. The test set produces some output. You can generally ignore the messages about skipped tests due to optional features which can't be imported. If a message is printed about a failed test or a traceback or core dump is produced, something is wrong. By default, tests are prevented from overusing resources like disk space and memory. To enable these tests, run "make testall". IMPORTANT: If the tests fail and you decide to mail a bug report, *don't* include the output of "make test". It is useless. Run the failing test manually, as follows: ./python -m test -v test_whatever (substituting the top of the source tree for '.' if you built in a different directory). This runs the test in verbose mode. Installing multiple versions ---------------------------- On Unix and Mac systems if you intend to install multiple versions of Python using the same installation prefix (--prefix argument to the configure script) you must take care that your primary python executable is not overwritten by the installation of a different version. All files and directories installed using "make altinstall" contain the major and minor version and can thus live side-by-side. "make install" also creates ${prefix}/bin/python3 which refers to ${prefix}/bin/pythonX.Y. If you intend to install multiple versions using the same prefix you must decide which version (if any) is your "primary" version. Install that version using "make install". Install all other versions using "make altinstall". For example, if you want to install Python 2.6, 2.7 and 3.5 with 2.7 being the primary version, you would execute "make install" in your 2.7 build directory and "make altinstall" in the others. Issue Tracker and Mailing List ------------------------------ We're soliciting bug reports about all aspects of the language. Fixes are also welcome, preferably in unified diff format. Please use the issue tracker: http://bugs.python.org/ If you're not sure whether you're dealing with a bug or a feature, use the mailing list: python-dev@python.org To subscribe to the list, use the mailman form: http://mail.python.org/mailman/listinfo/python-dev/ Proposals for enhancement ------------------------- If you have a proposal to change Python, you may want to send an email to the comp.lang.python or `python-ideas`_ mailing lists for initial feedback. A Python Enhancement Proposal (PEP) may be submitted if your idea gains ground. All current PEPs, as well as guidelines for submitting a new PEP, are listed at http://www.python.org/dev/peps/. .. _python-ideas: https://mail.python.org/mailman/listinfo/python-ideas/ Release Schedule ---------------- See PEP 478 for release details: http://www.python.org/dev/peps/pep-0478/ Copyright and License Information --------------------------------- Copyright (c) 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019 Python Software Foundation.

HISTORY OF THE SOFTWARE ========================== Python was created in the early 1990s by Guido van Rossum at Stichting Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands as a successor of a language called ABC. Guido remains Python's principal author, although it includes many contributions from others. In 1995, Guido continued his work on Python at the Corporation for National Research Initiatives (CNRI, see http://www.cnri.reston.va.us) in Reston, Virginia where he released several versions of the software. In May 2000, Guido and the Python core development team moved to BeOpen.com to form the BeOpen PythonLabs team. In October of the same year, the PythonLabs team moved to Digital Creations, which became Zope Corporation. In 2001, the Python Software Foundation (PSF, see https://www.python.org/psf/) was formed, a non-profit organization created specifically to own Python-related Intellectual Property. Zope Corporation was a sponsoring member of the PSF. All Python releases are Open Source (see http://www.opensource.org for the Open Source Definition). Historically, most, but not all, Python releases have also been GPL-compatible; the table below summarizes the various releases. Release Derived Year Owner GPL- from compatible? (1) 0.9.0 thru 1.2 1991-1995 CWI yes 1.3 thru 1.5.2 1.2 1995-1999 CNRI yes 1.6 1.5.2 2000 CNRI no 2.0 1.6 2000 BeOpen.com no 1.6.1 1.6 2001 CNRI yes (2) 2.1 2.0+1.6.1 2001 PSF no 2.0.1 2.0+1.6.1 2001 PSF yes 2.1.1 2.1+2.0.1 2001 PSF yes 2.1.2 2.1.1 2002 PSF yes 2.1.3 2.1.2 2002 PSF yes 2.2 and above 2.1.1 2001-now PSF yes Footnotes: (1) GPL-compatible doesn't mean that we're distributing Python under the GPL. All Python licenses, unlike the GPL, let you distribute a modified version without making your changes open source. The GPL-compatible licenses make it possible to combine Python with other software that is released under the GPL; the others don't. (2) According to Richard Stallman, 1.6.1 is not GPL-compatible, because its license has a choice of law clause. According to CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1 is "not incompatible" with the GPL. Thanks to the many outside volunteers who have worked under Guido's direction to make these releases possible. B.
