i keep getting error in rudimentary calculator program in python version 3.3.1. cannot find problem myself, can me? thank in advance!

    x=(input("which operation perform?"))         if x=='addition':         y=int(input("enter first number?"))         z=int(input("enter second number?"))         a=y+z         print(a)     elif x=='subtraction':         y=int(input("enter first number?"))         z=int(input("enter second number?"))         a=y-z         print(a)     elif x=='multiplication':         y=int(input("enter first number?"))         z=int(input("enter second number?"))         a=y*z         print(a) elif x=='division':         y=int(input("enter first number?"))         z=int(input("enter second number?"))         a=y/z         print(a)

your tabs messed think, try :

x=input("which operation perform?") if x=='addition':     y=int(input("enter first number?"))     z=int(input("enter second number?"))     a=y+z     print(a) elif x=='subtraction':     y=int(input("enter first number?"))     z=int(input("enter second number?"))     a=y-z     print(a) elif x=='multiplication':     y=int(input("enter first number?"))     z=int(input("enter second number?"))     a=y*z     print(a) elif x=='division':     y=int(input("enter first number?"))     z=int(input("enter second number?"))     a=y/z     print(a)
