Get the number of Python drives

https://docs.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-getlogicaldrives

Must be obtained as a function of the above address.

Python provides the default module, ctypes, so you can invoke the native library immediately.

import ctypes
bitmask = ctypes.windll.kernel32.GetLogicalDrives()
print("{0:b}".format(bitmask))

1100

The GetLogicalDrives function returns a result with a bitmask and determines whether each bit digit exists.

The result of the above code is 1100, so it means that there are no A, B, C, D drives.
