Problem using curly brackets in functions

Question

The line answer = int(input("What is {number1} * {number2} ?")) works fine when using without the function, but when I put it in functions, it throws the error Traceback (most recent call last): File "C:\Users\hjg\Downloads\test4.py", line 17, in <module> answer = eval(input("What is", number1, "*", number2, "?")) NameError: name 'number1' is not defined >>>.

import random, math

def quiz(answer):
    number1 = random.randint(0,9)
    number2 = random.randint(0,9)


    if answer == correctanswer:
        return print("Correct")
    else:
       return print("Incorrect.")


answer = int(input("What is {number1} * {number2} ?"))
correctanswer = number1 * number2


quiz(number1, number2)

Answer 1

You have to put the variable on top to make it global.

import random, math
number1 = random.randint(0,9)
number2 = random.randint(0,9)

def quiz(answer):
    correctanswer = number1 * number2
    if answer == correctanswer:
        return print("Correct")
    else:
       return print("Incorrect.")

answer = int(input(f"What is {number1} * {number2} ?"))
quiz(answer)
