  • What do you think `a == "rectangle" or "Rectangle" or "Rec" or "rec"` is equal to for different values of `a`? Also, is `"rectangle" or "Rectangle" or "Rec" or "rec"` a constant? – ForceBru Jul 13 '18 at 16:20

Use this:

if a in ["rectangle" ,"Rectangle" ,"Rec" ,"rec"]:

Same for the triangle.

This happens because in python

if a == 'x' or 'b' or 'c' or 'd'

is not the same as

if (a =='x') or (a =='b') or  (a == 'c') or ( a == 'd')
