Calculator in python

Question

I am trying to make calculator that can solve expressions with basic 4 operators, like 1+2*3-4/5, however it does not work and I do not know what is wrong. Please check my code.

Answer 1

I have an alternative to your code. The user can enter stuff like: 8*6/4-3+3 and this will still work. Very compact and if you want a command to exit out of the:

while True:

Just add:

if(y == "end" or y == "End"):
    break

And it will exit out of the "while True:"

Code (Python v3.3.0):

while True:
    x = "x="
    y = input(" >> ")
    x += y
    exec(x)
    print(x)
