Python receives `` from `input()` (newbie)

Question

I am trying to make my first program in Python, however, I am having a problem.

Why is op1 not being assigned the value I input?

print ("Hello user")
num1 = int(input("Choose a number: "))
num2 = int(input("Choose another number: "))
op1 = (input("Choose an operation [add, multiply, minus, divide]: "))
print (op1)

No matter what I enter into op1 I always receive this message from print (op1):

<function add at 0x10cff1938>

Is the error "NameError: name 'add' is not defined"? That would mean that you are using python2 not python3. — tdelaney, Nov 11 '15 at 19:11
In python 2, `input` evaluates a string as a python statement. `raw_input` is used to input strings. — tdelaney, Nov 11 '15 at 19:12
error is "" no matter what i input for 'op1' i always receive that error for 'print (op1)' — dandannn, Nov 11 '15 at 19:19

If you're using Python 2.7._, then if you're reading in strings, you need to use raw_input instead of input.

This code works for me, with python 3.4. Are you **sure** you're using python 3? – John Gordon Nov 11 '15 at 19:26
Hi John, i have just read another question with a similar problem. Turns out i am not running python 3. I downloaded and installed python 3.5 however, i am still running 2.7. Do you know how I can change this please? I am using mac. – dandannn Nov 11 '15 at 19:29
@dandannn: you can run `python3` or `python3.5` instead of just `python` to execute a specific version. You'll want to leave Python 2 as the system default. – Trey Hunner Nov 12 '15 at 01:51
