No operating system that I know has the concept of "overriding"
an existing directory.  If the directory that already exists is
good, just catch the OSError that mkdir raises with a try/except.
If you want to rename the existing directory then create a new
one of the same name, do so.  And so on, and so forth; your
description and implication of your desires and problems is
far too short and unclear for me to be of any more help.
