If you used one of the python.org installers for OS X, it installs into 
/Library/Frameworks/Python.framework.  /System/Library/Frameworks is 
where the Apple-supplied Pythons are located.  You should not attempt to 
alter or delete files there.

To use the new Python you should ensure that the framework bin directory 
is added to the front of your shell PATH environment variable.  For 
Python 2 installs, the installer does this automatically by default. For 
Python 3 installs, the installer does not.  However you can double-click 
the Update Shell Profile command in the /Applications/Python 3.3 folder.  
After it completes, open a new terminal window and you should find that 
python3.3 is now available.  You can also manually edit your 
.bash_profile or other relevant shell startup file:

PATH="/Library/Frameworks/Python.framework/Versions/3.3/bin:${PATH}"
export PATH
