This is Python version 3.3.5============================Copyright (c) 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011,2012, 2013, 2014 Python Software Foundation.  All rights reserved.Python 3.x is a new version of the language, which is incompatible with the 2.xline of releases.  The language is mostly the same, but many details, especiallyhow built-in objects like dictionaries and strings work, have changedconsiderably, and a lot of deprecated features have finally been removed.Build Instructions------------------On Unix, Linux, BSD, OSX, and Cygwin:New text    ./configure    make    make test    sudo make installThis will install Python as python3.You can pass many options to the configure script; run "./configure --help" tofind 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 shoulduse "make frameworkinstall" to do the installation.  Note that this installs thePython executable in a place that is not normally on your PATH, you may want toset 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.  Forexample:    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.)What's New----------We try to have a comprehensive overview of the changes in the "What's New inPython 3.3" document, found athttp://docs.python.org/3.3/whatsnew/3.3.htmlFor a more detailed change log, read Misc/NEWS (though this file, too, isincomplete, and also doesn't list anything merged in from the 2.7 release underdevelopment).If you want to install multiple versions of Python see the section belowentitled "Installing multiple versions".Documentation-------------Documentation for Python 3.3 is online, updated daily:http://docs.python.org/3.3/It can also be downloaded in many formats for faster access.  The documentationis downloadable in HTML, PDF, and reStructuredText formats; the latter versionis primarily for documentation authors, translators, and people with specialformatting requirements.If you would like to contribute to the development of Python, relevantdocumentation 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 tobe changed, such as optional warnings when deprecated features are used, andbackported versions of certain key Python 3.x features.A source-to-source translation tool, "2to3", can take care of the mundane taskof converting large amounts of source code.  It is not a complete solution butis complemented by the deprecation warnings in 2.6.  Seehttp://docs.python.org/3.3/library/2to3.html for more information.Testing-------To test the interpreter, type "make test" in the top-level directory.  The testset produces some output.  You can generally ignore the messages about skippedtests due to optional features which can't be imported.  If a message is printedabout 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 andmemory.  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 testmanually, as follows:        ./python -m test -v test_whatever(substituting the top of the source tree for '.' if you built in a differentdirectory).  This runs the test in verbose mode.Installing multiple versions----------------------------On Unix and Mac systems if you intend to install multiple versions of Pythonusing the same installation prefix (--prefix argument to the configure script)you must take care that your primary python executable is not overwritten by theinstallation of a different version.  All files and directories installed using"make altinstall" contain the major and minor version and can thus liveside-by-side.  "make install" also creates ${prefix}/bin/python3 which refers to${prefix}/bin/pythonX.Y.  If you intend to install multiple versions using thesame 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 3.3 with 2.7 being theprimary version, you would execute "make install" in your 2.7 build directoryand "make altinstall" in the others.Issue Tracker and Mailing List------------------------------We're soliciting bug reports about all aspects of the language.  Fixes are alsowelcome, preferable 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 themailing list:    python-dev@python.orgTo 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 thecomp.lang.python or python-ideas mailing lists for inital feedback.  A PythonEnhancement Proposal (PEP) may be submitted if your idea gains ground.  Allcurrent PEPs, as well as guidelines for submitting a new PEP, are listed athttp://www.python.org/dev/peps/.Release Schedule----------------See PEP 398 for release details:http://www.python.org/dev/peps/pep-0398/Copyright and License Information---------------------------------Copyright (c) 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011,2012, 2013, 2014 Python Software Foundation.
