The Mac-specific modules are documented in Mac OS X specific services. Python on Mac OS 9 or earlier can be quite different from Python on Unix or Windows, but is beyond the scope of this manual, as that platform is no longer supported, starting with Python 2.4. Aug 07, 2014  It can be old, especially on older versions of OSX. For example, OSX 10.6 (Snow Leopard) has Python 2.6 as system Python, where the current standard Python 2 version is 2.7. The alternative Pythons listed above are up to date with features and security fixes. It is just fine. Python may be installed in multiple places in your computer.

I want to completely remove Python 2.7 from my Mac OS X 10.6.4. I managed to remove the entry from the PATH variable by reverting my.bashprofile. But I also want to remove all directories, files.

OSX comes with a version of Python installed at /usr/bin/python. We'll callthis 'system Python'.

There are a variety of guides for working with Python on OSX (see list below),and all of them suggest installing another Python:

So - why do these guides suggest using a Python other than the one that comesinstalled on OSX by default?

There are various problems with system Python:

Python
  • It can be old, especially on older versions of OSX. For example, OSX 10.6(Snow Leopard) has Python 2.6 as system Python, where the current standardPython 2 version is 2.7. The alternative Pythons listed above are up todate with features and security fixes.
  • Updating OSX has the potential to change or break any updates you have madeto the Python installation, including installation of Python packages.
  • System Python has an unusual setup for some Python packages that makes itmuch more difficult to upgrade these packages

System Python and extra Python packages

Mac No Python Library Python 2.7 Bingo

Apple has kindly installed some optional Python packages into its Python, butdid that in a way that is not standard and therefore confusing to work with.

As y'all know, Python searches for packages using the module search path.

Here is the module search path for system Python:

The interesting entry is/System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/pythonbecause this entry is specific to system Python. Call this path'Extras/lib'. On a standard OSX 10.9 machine this directory contains some Python packages including the numerical packages numpy, scipy and matplotlib and other useful web packages including twisted.

If you, the user, install new packages in system Python, the packages will getwritten to /Library/Python/2.7/site-packages. As you can see from the pathlisting above, your newly installed package will therefore be lower in thePython module path than the packages in Extras/lib. That means that if youtry to install a new version of one of the packages in Extras/lib into system Python, system Python will ignore the version you installed and continue to use the version in Extras/lib.

Python

Apple presumably chose this setup because they use Python for system tasks,and they want to be able to depend on working versions of the packagesinstalled in Extras/lib. This is another reason to prefer another Python foryour daily Python work.
