How to install python 2.7.5 as 64bit?
Question: When downloading the python 2.7.5 [here](http://www.python.org/getit/), I
download the python installer with the link "Python 2.7.5 Mac OS X
64-bit/32-bit x86-64/i386 Installer (for Mac OS X 10.6 and later [2])".
Installed the python, I cd the directory
"/Library/Frameworks/Python.framework/Versions/2.7" and execute the following
python code:

    
    
     import sys
     print sys.maxint
    

and I get 2147483647 which means I am runing the python of 32bit version. How
can I install the python of 64bit version?


Answer: Make sure you are really running the Python you think you are. `cd
/Library/Frameworks/Python.framework/Versions/2.7` doesn't help by itself. If
you did not change any of the default installer options,
`/Library/Frameworks/Python.framework/Versions/2.7/bin` should now be first in
your shell `PATH` (you need to open a new terminal window after installing to
see this) and there should now be `python` and `python2.7` links in
`/usr/local/bin` to the new Python.

    
    
    $ which python
    /Library/Frameworks/Python.framework/Versions/2.7/bin/python
    $ python
    Python 2.7.5 (v2.7.5:ab05e7dd2788, May 13 2013, 13:18:45)
