Changing file names

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.

os.rename(oldna me, newname)

found under "files and directories" in the library reference:

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.

Hi all, I know now how to change the font name of a RTF file in a RTB control using, for example: RTextBox1.SelFontName = cmbFonts.Text I have a RTF file -created with Word- displayed in a RTB control. Whenever I change the font type during the runtime by selecting a font name from a combobox -of all system fonts, the text changes its font correctly but I loose some formatting such as a bold text and/or titles become normal text.

Hi! This is in Python 2.3.4 under WinXP. I have a situation where I think changing the behaviour of a namespace would be very nice. The goal is to be able to run a python file from another in a separate namespace in such a way that a NameError is not raised if a non-existing variable is used in the file. The file that I want to run is taken out of context, and some needed variables may be missing that are normally there when used in...
