How do I get user input from the keyboard in Python 2?

Question

I wrote a function in Python which prompts the user to give two numbers and adds them. It also prompts the user to enter a city and prints it. For some reason, when I run it in

Answer 1

If you're on Python 2, you need to use raw_input:

def func_add(num1, num2):

   a = raw_input("your city")
   print a
   return num1 + num2 

input causes whatever you type to be evaluated as a Python expression, so you end up with

a = whatever_you_typed

So if there isn't a variable named whatever_you_typed you'll get a NameError.

With raw_input it just saves whatever you type in a string, so you end up with

a = 'whatever_you_typed'

which points a at that string, which is what you want.
