Need help in Python 2.7

[Ethan97]

So im trying to learn Python and im using 2.7 becasue my Python videos use that and its working and so I am trying to write my second little program its a calculator which takes integer input from the user and chooses a function heres my shot at it and it works:

 

num1 = input("Enter first number")

input("Pick a function add,subtract,divide or multiply")

num2 = input("Enter second number")

 

so this ^ works it does what its supposed to takes the input but the function part isnt exactly there as I am struggling with that so I want to ask is there a way for example when the User inputs the function Add I want the code to recognise that the User has entered that function and carry it out as a normal calculator does, don't ask why I'm doing a calculator I just want to learn thanks guys

num1 = input("Enter first number") x=input("Pick a function add,subtract,divide or multiply") num2 = input("Enter second number") if x=="add":        answer = num1+num2 print answer 

k try this
