I'm going to close this as not a bug. Feel free to reopen it if there's use 
case for passing in None.

[issue21336] ntpath.splitdrive fails on None argument

[Ben Ma]

New submission from Ben Ma:

 import ntpath
 ntpath.splitdrive(None)
Traceback (most recent call last):
  File stdin, line 1, in module
  File E:\python3\lib\ntpath.py, line 159, in splitdrive
if p and len(p)  1:
TypeError: object of type 'NoneType' has no len()

Solution: (that I've found)

Lib/ntpath.py
#in function splitdrive
...
empty = _get_empty(p)
+++ if p and len(p)  1:
--- if len(p)  1:
sep = _get_sep(p)
...
return p[:2], p[2:]
+++ else:
+++ p = ''
return empty, p
...

Eric V. Smith added the comment:

Why are you passing None, and what would you expect the result to be?

The function is documented as taking a string.
