How to use switch/case in python?

[ichabod801]

There is no switch/case statement in Python. Use if/elif instead or a data structure. You did use a data structure, but I would do it this way:

operators = {'1': add, '2': subtract, '3': divide, '4': multiply, '5': increase}
...
if choice in operators:
    print(operators[choice](a, b))
