Hi "Nop",

The behaviour of these functions is described in the documentation, for
example in

Return a copy of s, but with upper case letters converted to lower case. 

In this particular case, the docstring of the function has just as much

>>> string.lower.__doc__
'lower(s) -> string\n\n    Return a copy of the string s converted to
lowercase.\n\n    '

If you're looking at additional info for _how_ exactactly these
functions are implemented, then the source code is the only info there
is. Btw. in current Python versions the string module just delegetages
to the string methods, which are the preferred option. So you could just
as well use.

You're not supposed to delete modules from the standard library.  If you
don't want your Python to fail in obscure ways, you'd better get that
file back into place. Btw.  my Python 2.1.3 and 2.2.1 starts up fine
even without the string module.
