See os.mkdir() or os.makedirs().
Please be *very* careful letting users access the file system in this
way. Consider the situation where the user enters "/HELLO",
"../../HELLO" etc - they could do all sorts of damage! You should
probably restrict directory creation to a certain area of the file
system. os.path.normpath() can be useful in working out what the user's
input really means.

Unless you have created an object reference called file then file is
actually a builtin for *opening* a file, or rather for creating a file
This is probably what you want:
or better still
f = file('thefile.txt','wt')
which will ensure the file is closed correctly.
