Getting and installing the latest version of Python
 | 
						|
===================================================
 | 
						|
 | 
						|
On Linux
 | 
						|
--------
 | 
						|
 | 
						|
Python comes preinstalled on most Linux distributions, and is available as a
 | 
						|
package on all others.  However there are certain features you might want to use
 | 
						|
that are not available on your distro's package.  You can easily compile the
 | 
						|
latest version of Python from source.
 | 
						|
 | 
						|
In the event that Python doesn't come preinstalled and isn't in the repositories as
 | 
						|
well, you can easily make packages for your own distro.  Have a look at the
 | 
						|
following links:
 | 
						|
 | 
						|
.. seealso::
 | 
						|
 | 
						|
   http://www.debian.org/doc/manuals/maint-guide/first.en.html
 | 
						|
      for Debian users
 | 
						|
   http://en.opensuse.org/Portal:Packaging
 | 
						|
      for OpenSuse users
 | 
						|
   http://docs.fedoraproject.org/en-US/Fedora_Draft_Documentation/0.1/html/RPM_Guide/ch-creating-rpms.html
 | 
						|
      for Fedora users
 | 
						|
   http://www.slackbook.org/html/package-management-making-packages.html
 | 
						|
      for Slackware users
 | 
						|
 | 
						|
 | 
						|
On FreeBSD and OpenBSD
 | 
						|
----------------------
 | 
						|
 | 
						|
* FreeBSD users, to add the package use::
 | 
						|
 | 
						|
     pkg_add -r python
 | 
						|
 | 
						|
* OpenBSD users use::
 | 
						|
 | 
						|
     pkg_add ftp://ftp.openbsd.org/pub/OpenBSD/4.2/packages/<insert your architecture here>/python-<version>.tgz
 | 
						|
 | 
						|
  For example i386 users get the 2.5.1 version of Python using::
 | 
						|
 | 
						|
     pkg_add ftp://ftp.openbsd.org/pub/OpenBSD/4.2/packages/i386/python-2.5.1p2.tgz
 | 
						|
 | 
						|
 | 
						|
On OpenSolaris
 | 
						|
--------------
 | 
						|
 | 
						|
To install the newest Python versions on OpenSolaris, install `blastwave
 | 
						|
<http://www.blastwave.org/howto.html>`_ and type ``pkg_get -i python`` at the
 | 
						|
prompt.
 | 
						|
 | 
						|
 | 
						|
Building Python
 | 
						|
===============
 | 
						|
 | 
						|
If you want to compile CPython yourself, first thing you should do is get the
 | 
						|
`source <http://python.org/download/source/>`_. You can download either the
 | 
						|
latest release's source or just grab a fresh `clone
 | 
						|
<http://docs.python.org/devguide/setup#getting-the-source-code>`_.  (If you want
 | 
						|
to contribute patches, you will need a clone.)
 | 
						|
 | 
						|
The build process consists in the usual ::
 | 
						|
 | 
						|
   ./configure
 | 
						|
   make
 | 
						|
   make install
 | 
						|
 | 
						|
invocations. Configuration options and caveats for specific Unix platforms are
 | 
						|
extensively documented in the :source:`README` file in the root of the Python
 | 
						|
source tree.
 | 
						|
 | 
						|
.. warning::
 | 
						|
 | 
						|
   ``make install`` can overwrite or masquerade the :file:`python3` binary.
 | 
						|
   ``make altinstall`` is therefore recommended instead of ``make install``
 | 
						|
   since it only installs :file:`{exec_prefix}/bin/python{version}`.
 | 
						|
 | 
						|
 | 
						|
Python-related paths and files
 | 
						|
==============================
 | 
						|
 | 
						|
These are subject to difference depending on local installation conventions;
 | 
						|
:envvar:`prefix` (``${prefix}``) and :envvar:`exec_prefix` (``${exec_prefix}``)
 | 
						|
are installation-dependent and should be interpreted as for GNU software; they
 | 
						|
may be the same.
 | 
						|
 | 
						|
For example, on most Linux systems, the default for both is :file:`/usr`.
 | 
						|
 | 
						|
+-----------------------------------------------+------------------------------------------+
 | 
						|
| File/directory                                | Meaning                                  |
 | 
						|
+===============================================+==========================================+
 | 
						|
| :file:`{exec_prefix}/bin/python3`             | Recommended location of the interpreter. |
 | 
						|
+-----------------------------------------------+------------------------------------------+
 | 
						|
| :file:`{prefix}/lib/python{version}`,         | Recommended locations of the directories |
 | 
						|
| :file:`{exec_prefix}/lib/python{version}`     | containing the standard modules.         |
 | 
						|
+-----------------------------------------------+------------------------------------------+
 | 
						|
| :file:`{prefix}/include/python{version}`,     | Recommended locations of the directories |
 | 
						|
| :file:`{exec_prefix}/include/python{version}` | containing the include files needed for  |
 | 
						|
|                                               | developing Python extensions and         |
 | 
						|
|                                               | embedding the interpreter.               |
 | 
						|
+-----------------------------------------------+------------------------------------------+
 |

 | 
						|
Miscellaneous
 | 
						|
=============
 | 
						|
 | 
						|
To easily use Python scripts on Unix, you need to make them executable,
 | 
						|
e.g. with ::
 | 
						|
 | 
						|
   $ chmod +x script
 | 
						|
 | 
						|
and put an appropriate Shebang line at the top of the script.  A good choice is
 | 
						|
usually ::
 | 
						|
 | 
						|
   #!/usr/bin/env python3
 | 
						|
 | 
						|
which searches for the Python interpreter in the whole :envvar:`PATH`.  However,
 | 
						|
some Unices may not have the :program:`env` command, so you may need to hardcode
 | 
						|
``/usr/bin/python3`` as the interpreter path.
 | 
						|
 | 
						|
To use shell commands in your Python scripts, look at the :mod:`subprocess` module.
 | 
						|

Editors
 | 
						|
=======
 | 
						|
 | 
						|
Vim and Emacs are excellent editors which support Python very well.  For more
 | 
						|
information on how to code in Python in these editors, look at:
 | 
						|
 | 
						|
* http://www.vim.org/scripts/script.php?script_id=790
 | 
						|
* http://sourceforge.net/projects/python-mode
 | 
						|
 | 
						|
Geany is an excellent IDE with support for a lot of languages. For more
 | 
						|
information, read: http://www.geany.org/
 | 
						|
 | 
						|
Komodo edit is another extremely good IDE.  It also has support for a lot of
 | 
						|
languages. For more information, read:
