How to print Python installation directory to the output?

Question

Let's say Python is installed in the location

C:\TOOLS\COMMON\python\python252

I want to print this location in the output of my program. Please let me know can I do this.

Answer 1

you can use

import sys, os
os.path.dirname(sys.executable)

but remember than in Unix systems the "installation" of a program is usually distributed along the following folders:

• /usr/bin (this is what you'll probably get)
• /usr/lib
• /usr/share
• etc.

Answer 2

Maybe either of these will satisfy you:

>>> import sys
>>> print(sys.prefix)
/usr
>>> print(sys.path)
['', '/usr/lib/python25.zip', '/usr/lib/python2.5', '/usr/lib/python2.5/plat-linux2',
'/usr/lib/python2.5/lib-tk', '/usr/lib/python2.5/lib-dynload', 
'/usr/local/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages', 
'/usr/lib/python2.5/site-packages/Numeric', '/usr/lib/python2.5/site-packages/gst-0.10',
'/var/lib/python-support/python2.5', '/usr/lib/python2.5/site-packages/gtk-2.0', 
'/var/lib/python-support/python2.5/gtk-2.0']
