Thanks a lot for the detailed help. Well, I have now got atleast basics
of functions, will be doing some more reading on it in nex
Wow! I checked the list at lunchtime and there were only a few things
here, then I check again now and lots of stuff from my tutor! Fortunately

If you were executing
f(4)
in a program/script, the return value would be lost.

too.
But I am not getting functions exactly. I mean what is the difference between,
def func():
and
def func(x):
When to use which? (please do not say "returns a value" for I do not un
