Python to have multiple correct answers

Question

I am trying to have multiple answers to 1 question. How can I make that happen here?
I want all numbers between 10 and 20 to be correct, while everything else to be wrong:

print ("Say a number between 10 or 20 "
       "Only full numbers")

answer = 0

while answer != "10":

    answer = input()
    if answer == '10':
        print("Right!")
    else:
        print ("Wrong try again!")

Answer 1

Cast to int, then compare:

answer = int(input())
if 10 <= answer <= 20:
    print("Right!")
else:
    print ("Wrong try again!")
