While Loop - Not Equal - Python, Not Evaluating Correctly?

Question

Created a little program that generates two values between 1 and 10 (inclusive), and prompts the user to find the sum as an answer.

I'm trying to use a while loop here. It seems that the code "while (numb1 + numb2 != answer)" will always evaluate to true (even when false), and so the loop never exits.

Wondering what I might have missed? Would appreciate any input!

import random
numb1 = random.randint(1,10)
numb2 = random.randint(1,10)

print('What is: ', numb1, ' + ', numb2, '?')
answer = input('Answer: ')

while (numb1 + numb2 != answer):
    print('Incorrect, try again!')
    answer = input('Answer: ')
print('Correct!')

input returns a string, but numb1 and numb2 are integers. Cast to an int before comparing: answer = int(input('Answer: ')) — 0x5453

That's it, thanks! I thought "input" was for integers and "raw_input" was for strings. Guess I misunderstood this. Thank you. — x kj 283'

answer is a str while numb1 and numb2 are ints.

>>> 1 == "1"
False

Do this:

while numb1 + numb2 != int(answer):

Because you comparing int values with str values, which cannot be equal in any case.

Before comparison convert answer to int with

answer = int(input('Answer: '))
