get the windows installation drive using python

How to detect the wi开发者_JS百科ndows installation path or drive using python code ?

>>> import os
>>> os.environ['SYSTEMDRIVE']
'C:'

You can use GetWindowsDirectory via the ctypes library to get the location of the Windows folder, and then you can use os.path.splitdrive to get the drive letter. For example:

import ctypes
import os

kernel32 = ctypes.windll.kernel32
windows_directory = ctypes.create_unicode_buffer(1024)
if kernel32.GetWindowsDirectoryW(windows_directory, 1024) == 0:
    # Handle error
else:
    windows_drive = os.path.splitdrive(windows_directory)[0]

You can use the WINDIR enviroment variable.

os.environ['WINDIR']

Use this code to just get the letter, and nothing else:

import os
os.environ['WINDIR'].split(":\\")[0]

Example output:

>>> os.environ['WINDIR'].split(":\\")[0]

'C'
