Best way to strip punctuation from a string
...g to beat
s.translate(None, string.punctuation)
For higher versions of Python use the following code:
s.translate(str.maketrans('', '', string.punctuation))
It's performing raw string operations in C with a lookup table - there's not much that will beat that but writing your own C code.

...unuser -
more on this later.

there is setuid in Python:
import os
os.setuid(501) # UID of my_user is 501
I still don't think you can setuid

Copy file or directories recursively in Python
Python seems to have functions for copying files (e.g. shutil.copy ) and functions for copying directories (e.g. shutil.copytree ) but I haven't found any function that handles both. Sure, it's trivial to check whether you want to copy a file or a directory, but it seems like a strange omission.
