How to handle input() within functions in Python

Question

I have the following code snippet:

while True:
print("Enter 'a' to add two numbers")
...
user_input = raw_input('Users Choice: ') #I'm using py2 so raw_input works here

def getNumbers():
print('Enter first number')
num1 = input()
print('Enter second number')
num2 = input()
...

if user_input == 'a':
getNumbers()
num3 = str(num1 + num2)
print('The answer is: ' + num3 + '\n\n')

The function is meant to take in an input from the user then the following code is meant to combine num1 and num2 into a solution.

Anybody know what I did wrong?
(Also if your looking for the rest of the code, it's just a simple calculator. I'm worried about functions that can handle input and if that's even possible)

Answer 1

I was trying to make the function do too much, I changed the code to:

print('Enter first number and press \'enter\' key')
print('Enter second number and press \'enter\' key')

def getNumbers(num1, num2):
print(str(num1 + num2))

getNumbers(int(input()),int(input()))

~ swim ~ That's what I was looking for, Thanks

I realized that the function was trying to do too many different things, If I wanted this to work as intended I would have to use the print statements outside of the function. Even then I would get something like:

Enter your first number:
Enter your second number:
3
4
Answer: 7 #The calculation happens outside of the function

and im looking for something like:

Enter your first number:
3
Enter your second number:
4

~ swim ~ Mostly, I dont think its possible to get what I described above without excessive code. Im trying to nail down what I can and cant do with functions and I didnt see any documentation on input being handled the way I described. Thanks for the support!

Answer 5

@Pulkit Kamboj - While that would prevent the use of other datatypes other than int, That wasnt the solution.

@- swim - - Ive updated the title and the code so that you have access to the basics

Answer 6

Evan Martine can you please give the whole code

Answer 7

Im using python 2.7 @- swim -

Answer 8

Use num1=int(input())
Same for num2
