os.chown()

[James Colannino]

Hey everyone.  I tried to use os.chown() in the following manner:

os.chown('filename', 'username', 'groupname')

I got an error, and when I googled for this function I realized that I 
must pass the numerical uid and gid.  My question is, is there a way for 
me to change ownership based on the name instead of the number?  Perhaps 
there's a function that will let me lookup the uid from the username, 
and the gid from the groupname?

Thanks :)

James
