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.
|
|
|
|
|
|
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.)
|
|
|
|
|
|
What's New
|
|
----------
|
|
|
|
We try to have a comprehensive overview of the changes in the "What's New in
|
|
Python 3.2" document, found at
|
|
|
|
http://docs.python.org/3.2/whatsnew/3.2.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 3.2 is online, updated daily:
|
|
|
|
http://docs.python.org/3.2/
|
|
|
|
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.
|
|
|
|
|
|
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/3.2/library/2to3.html for more information.
|
|
|
|
|
|
Testing
|
|
-------
|
|
|
|
To test the interpreter, type "make test" in the top-level directory. This runs
|
|
the test set twice (once with no compiled files, once with the compiled files
|
|
left by the previous test run). 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 2.5, 2.6 and 3.2 with 2.6 being the
|
|
primary version, you would execute "make install" in your 2.6 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, 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 the
|
|
mailing list:
|
|
|
|
python-dev@python.org
|
|
|
|
To subscribe to the list, use the mailman form:

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 inital 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/.
