Reverse of os.path.normcase on Windows

Question

Is there a simple way to get the "real" case sensitive path from a all lower case path. Like the reverse of os.path.normcase.

For example, consider the directory:

c:\StackOverFlow

If I have the following snippet, how to obtain d_real?

>>> import os
>>> d = os.path.normcase('C:\\StackOverFlow') # convert to lower case
>>> d
'c:\\stackoverflow'
>>> d_real = ... # should give 'C:\StackOverFlow' with the correct case

Answer 1

I wouldn't consider this solution simple, but what you can to is:

import os
d = os.path.normcase('C:\\StackOverFlow')
files = os.listdir(os.path.dirname(d))
for f in files:
  if not d.endswith(f.lower()):
    continue
  else
    real_d = os.path.join(os.path.dirname(d), f)

It's probably not efficient (depending on the number of files in the directory). It needs tweaking for the path-components (my solution really only corrects the case of the file name and doesn't care about the directory names). Also, maybe os.walk could be helpful to traverse down the tree.
