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.)
