Find where python is installed (if it isn't default dir)

Question

Python is on my machine, I just don't know where, if I type python in terminal it will open Python 2.6.4, this isn't in it's default directory, there surely is a way of finding it's install location from here?

Answer 1

sys has some useful stuff:

$ python
Python 2.6.6 (r266:84297, Aug 24 2010, 18:13:38) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.executable
'c:\Python26\python.exe'
>>> sys.exec_prefix
'c:\Python26'
>>>
>>> print '
'.join(sys.path)
