A system independent way using python to get the root directory/drive on which python is installed

Question

For Linux this would give me /, for Windows on the C drive that would give me C:\\. Note that python is not necessarily installed on the C drive on windows.

Answer 1

Try this:

import os  def root_path():     return os.path.abspath(os.sep) 

On Linux this returns /

On Windows this returns C:\\ or whatever the current drive is

Answer 2

You can get the path to the Python executable using sys.executable:

>>> import sys >>> import os >>> sys.executable '/usr/bin/python' 

Then, for Windows, the drive letter will be the first part of splitdrive:

>>> os.path.splitdrive(sys.executable) ('', '/usr/bin/python')
