Find System Hard Disk Drive from Python?

Question

I am working on a software installer for my current application. It needs to be installed to the System HDD. How owuld I detect the system drive and return the letter from Python?

Would the win32 extensions be useful? How about the os module pre packaged with Python?

Answer 1

This is how to return the letter of the System drive on a Win32 platform:

import os
print os.getenv("SystemDrive")

The above snippet returns the system drive letter. In my case ( and most cases on windows) C:

Answer 2

If you install the win32 extensions, the following will get you the information you want:

In [82]: import win32api

In [83]: drives = win32api.GetLogicalDriveStrings()

In [84]: drives
Out[84]: 'C:\\\x00D:\\\x00E:\\\x00'

In [85]: drives.split('\x00')
Out[85]: ['C:\\', 'D:\\', 'E:\\', '']

Ignore the last item, due to a terminating character in the string returned by win32's GetLogicalDriveStrings function.
