Howeve, it doesnt seem to be working. It doesnt calculate the bill. I dont know what to do, as I'm less than average at this.
it comes up as IndexError: list index out of range at line42

Please help

Those lists you define are indexed from 0, not 1 as you seem to assume. 
(So you get an index error if choosing pizza type 5).

You might try inserting a dummy 0 at the start (so the rest are indexed 
from 1), but better to change the logic.

Also total_cost_cal() is not defined anywhere. (And the user interface 
is generally untidy with poor error checking, but this can be cleaned up 
later.)

(I also found I was obliged to choose an extra topping. Suppose I don't 
want one? There is no option for that. Perhaps you can use option 0 for 
some of these, and that might help solve the indexing problem.)

Don't know which one is line 42; but I'd bet your problem is there.
As a rough guess, it might be the line that says:
  pizza_cost = pizzatype[menu]

You're bounding that to the range 1-5.  A Python list of length 5 has
indices 0-4.

But the error message is telling you everything you need to know; you're
trying to get a list index that's out of range in line 42. Find line
42, figure out what index you're asking it for, and you'll have your
answer. If you don't have an editor that shows you line numbers then
your editor is fundamentally terrible and you should not use it (I
personally like Notepad++ for Windows or Geany for Linux).

As it has already been pointed out, a Python list starts with an index
of 0.  Change the last line in the above code to this...

    pizza_cost = pizzatype[menu - 1]

Anywhere else that your code references a list index you may need to
make the same change.

Then try entering one line at a time of your program into the
interactive interpreter.  Copy and paste is fine, but use the
interpreter to look at the actual values of variables that you're
creating.

Also, as a mailing list/Usenet etiquette note: You get to have one name
you go by.  Going around changing the name you're posting under in the
middle of the thread is a guaranteed way to piss folks off.  You didn't
know.  You now do.
