question about modules

[Jon]

Hi Jeff,

That makes sense -- thanks.  However now when I use "re.capwords (sentence)"
I get a different error message:

AttributeError: 'module' object has no attribute 'capwords'

Each of the other two suggested implimentations produce a similar error
message.  Is there something even more basic that I am failing to do?  I'm
using the IDLE GUI in WinXP, Python release 2.4...

Thanks!
Jon
