Strings, ints, and operators in Python

Question

How can I use an arithmetic operator (input by the user as a string) in an operation? I can print the operation itself, but I want to print the solution!

Here\'s my clum

Answer 1

Use the operator module, which has functions that perform the same operations as your arithmetic operations.

import operator
ops = {'*': operator.mul, '/': operator.div, '+': operator.add, '-': operator.sub}

op = input("Please enter  *,  /,  +,  or  - : ")
result = ops[op](x, y)
