eval not working in code

[jamminjamie]

Hello,

I am new to Python and am working on a project to build a calculator. I am using Pycharm to build this. Eval does not work in the code for the calculator, however, if I do a simple eval statement like x = 1 and print(eval('x + 1')) it works. Any idea why? Here is code:

import re

print("Our Magic Calculator")
print("Type 'quit' to exit\n")

previous = 0
run = True

def performMath():
    global run
    global previous
    equation = input("Enter equation:")
    if equation == 'quit':
        run = False
    else:
        previous = eval(equation)
        print(equation)

while run:
    performMath()

---

Figured it out...I had print(equation) not print(previous) DUH!
