How can I get the name of a drive in python

Why don't you use win32api.GetVolumeInformation?

import win32api
win32api.GetVolumeInformation("C:\\")

outputs

('WINDOWS', 1992293715, 255, 65470719, 'NTFS')

Try the GetVolumeInformation function instead. It returns the volume label directly.

Using the above fragment, I filled in the missing(optional, null) arguments as a quick helper:

import ctypes
kernel32 = ctypes.windll.kernel32
volumeNameBuffer = ctypes.create_unicode_buffer(1024)
fileSystemNameBuffer = ctypes.create_unicode_buffer(1024)
serial_number = None
max_component_length = None
file_system_flags = None

rc = kernel32.GetVolumeInformationW(
    ctypes.c_wchar_p("F:\\"),
    volumeNameBuffer,
    ctypes.sizeof(volumeNameBuffer),
    serial_number,
    max_component_length,
    file_system_flags,
    fileSystemNameBuffer,
    ctypes.sizeof(fileSystemNameBuffer)
)

print volumeNameBuffer.value
print fileSystemNameBuffer.value

This should be copy-and-paste-able.
