Changing file names

[Thomas Philips]

I want to get a list of all subdirectories of a given directory, and
within each directory, change the name of each file using a
predetermined rule.

The function glob in module glob will give me a list of all the
subdirectories, and by looping over this list and repeatedly calling
glob, I can create lists of files within each directory, which are
easily edited to create lists of new filenames.

How then can I change the existing filenames to these new filenames?
What python functions should I be using, and what modules are they
contained in?

See "rename", obviously.

There is a "rename" function in the "os" module.

Sounds like you want to use os.path.walk function
which recursively drills down through directories and
subdirectories. Then (as everyone else has pointed
out). You can use os.rename.
