NAME
python, pythonw -- an interpreted, interactive, object-oriented programming language SYNOPSIS
python ... pythonw ... DESCRIPTION
To support multiple versions, the programs named python and pythonw now just select the real version of Python to run, depending on various settings. (As of Python 2.5, python and pythonw are interchangeable; both execute Python in the context of an application bundle, which means they have access to the Graphical User Interface; thus both can, when properly programmed, display windows, dialogs, etc.) The current supported versions are 2.6 and 2.7, with the default being 2.6. Use % man python2.6 % man python2.7 % man pythonw2.6 % man pythonw2.7 to see the man page for a specific version. Without a version specified, % man pydoc and the like, will show the man page for the (unmodified) default version of Python (2.6). To see the man page for a specific version, use, for example, % man pydoc2.7 CHANGING THE DEFAULT PYTHON
Using % defaults write com.apple.versioner.python Version 2.7 will make version 2.7 the user default when running the both the python and pythonw commands (versioner is the internal name of the version- selection software used). To set a system-wide default, replace 'com.apple.versioner.python' with '/Library/Preferences/com.apple.versioner.python' (admin privileges will be required). The environment variable VERSIONER_PYTHON_VERSION can also be used to set the python and pythonw version: % export VERSIONER_PYTHON_VERSION=2.7 # Bourne-like shells or % setenv VERSIONER_PYTHON_VERSION 2.7 # C-like shells % python ... This environment variable takes precedence over the preference file settings. 64-BIT SUPPORT Versions 2.6 and 2.7 support 64-bit execution (which is on by default). Like the version of Python, the python command can select between 32 and 64-bit execution (when both are available). Use: % defaults write com.apple.versioner.python Prefer-32-Bit -bool yes to make 32-bit execution the user default (using '/Library/Preferences/com.apple.versioner.python' will set the system-wide default). The environment variable VERSIONER_PYTHON_PREFER_32_BIT can also be used (has precedence over the preference file): % export VERSIONER_PYTHON_PREFER_32_BIT=yes # Bourne-like shells or % setenv VERSIONER_PYTHON_PREFER_32_BIT yes # C-like shells Again, the preference setting and environmental variable applies to both python and pythonw. USING A SPECIFIC VERSION
Rather than using the python command, one can use a specific version directly. For example, running python2.7 from the command line will run the 2.7 version of Python, independent of what the default version of Python is. One can use a specific version of Python on the #! line of a script, but that may have portability and future compatibility issues. Note that the preference files and environment variable that apply to the python command, do not apply when running a specific version of Python. In particular, running python2.6 will always default to 64-bit execution (unless one uses the arch(1) command to specifically select a 32-bit architecture). SEE ALSO

NAME
dh_pysupport - use the python-support framework to handle Python modules SYNOPSIS
dh_pysupport [debhelper options] [-V X.Y] [-X item [...]] [-n] [module dirs ...] DESCRIPTION
dh_pysupport is a debhelper program that will scan your package, detect public modules in /usr/lib/pythonX.Y/site-packages, and move them to the shared Python modules location. It will generate appropriate postinst/prerm scripts to byte-compile modules installed there for all available python versions. It will also look for private Python modules and will byte-compile them with the current Python version. You may have to list the directories containing private Python modules. If a file named debian/pyversions exists, it is used to determine the python versions with which the package can work. Appropriate dependencies on python-support, python and pythonX.Y are put in ${python:Depends}. The ${python:Versions} and ${python:Provides} optional substitution variables are made available as well. OPTIONS
module dirs If your package installs private python modules in non-standard directories, you can make dh_pysupport check those directories by passing their names on the command line. By default, it will check /usr/lib/$PACKAGE, /usr/share/$PACKAGE, /usr/lib/games/$PACKAGE and /usr/share/games/$PACKAGE -n, --noscripts Do not modify postinst/postrm scripts. -d This option is deprecated. -V X.Y Force private modules to be bytecompiled with the specific X.Y python version, regardless of the default python version on the system. -X item, --exclude=item Exclude files that contain "item" anywhere in their filename from being taken into account to generate the python dependency. It also excludes them from byte-compilation. You may use this option multiple times to build up a list of things to exclude. CONFORMS TO
