This is the high-level shutil module, so why not try to use the resolved parent
directory? For example:
def disk_usage(path):
try:
total, free = nt._getdiskusage(path)
except NotADirectoryError:
path = os.path.dirname(nt._getfinalpathname(path))
total, free = nt._getdiskusage(path)
used = total - free
return _ntuple_diskusage(total, used, free)
Also, as noted in msg260022, nt._getdiskusage was overlooked when implementing
PEP 529. The same applies to nt._getfinalpathname and nt._getvolumepathname.
nt._getfullpathname works with bytes because it takes an argument-clinic
`path_t` instead of `unicode` or `Py_UNICODE`. I think the other 3 should be
rewritten to use path_t, but it's out of scope for this issue.
