Need a function. Any built-in function or module for this?

[wcc]

Thanks you very much Paul.  I think I have a little more homework to
do.
1. The upper case letter may not be the first letter in each word.
2. There may be more than one (continous) upper case letters in one
word.
I just wanted to find out if there is something already there in python
built-in functions, modules.  Thanks again.
