I have read Xah Lee's post so that you don't have to.

Shorter Xah Lee:

    "I don't know Python very well, and rather than admit I made
     some pretty lousy design choices in my code, I blame Python.
     And then I cross-post about it, because I'm the most important 
     person in the Universe."


When the only tool you know how to use is a hammer, everything looks like 
a nail. Instead of using regexes ("now you have two problems"), use the 
right tool: to count path components, split the path, then count the 
number of path components directly.

import os
components = os.path.split(some_path)
print len(components)

No matter what separator the OS users, os.path.split will do the right 
thing. There's no need to mess about escaping separators so you can 
hammer it with the regex module, when Python comes with the perfectly 
functional socket-wrench you actually need.
