Python cant recognize the if - Statement

im very new in Coding and i started with Python to understand how to code. Im going to programm a simply quiz, where the User choose which Quiz they want to play. I did it the an input() and yet it does not goto the if - Statement. Code:

import quiz1
import quiz2
import quiz3
import quiz4

quiz = input("Please choose which Quiz you want to play (1-4): ")
print(quiz)

if quiz == 1:
        quiz1
        #f1 = open(fragebogen1.py)
        #print(f1)
elif quiz == 1:
        print("hello")
elif quiz == 3:
        print("hello")
elif quiz == 4:
        print("hello")

Thanks in advance
