Yes. Don't remove Apple's copy of python, it is used by the OS itself  
and 3th party applications rely on it being there.

Multiple python installations on a single machine are perfectly safe,  
although it can be confusing when you don't know about all of them and  
you accicently invoke a different version of python that you thought  
you would.

This are part of the system install

These are site-packages directorys for python 2.3 and python 2.5

This is the system install of python and contains the installations  
for python 2.5 and 2.3 (the former is not present on 10.3).

Other common locations of a python installation are /Library/ 
Frameworks/Python.framework (the python.org distribution of python, as  
well as ActiveState's python), /opt/local/bin (MacPorts) and /sw/bin  
(Fink).
