这个乘法测试生成器中的 if 语句有什么问题？

Question

This is a multiplication test generator. When I enter the correct answer, it still displays the message "No. Please try again."

import random

answer = 0

def generate_numbers():
    num1 = random.randrange(0,10)
    num2 = random.randrange(0,10)
    return(num1, num2)

def display_question(answer):
    num1, num2 = numbers
    answer = num1 * num2
    guess = int(input(f'What is {num1} times {num2}?'))
                
    while guess != answer:
        print("No. Please try again")
        display_question()

    print("Very good!")

Answer 1

Not sure why you are using answer as argument but this should work:-

import random

def generate_numbers():
    num1 = random.randrange(0,10)
    num2 = random.randrange(0,10)
    return(num1, num2)

def display_question():
    num1, num2 = generate_numbers()
    answer = num1 * num2
    guess = int(input(f'What is {num1} times {num2} ?\n'))
                
    if guess != answer:
        print("No. Please try again\n")
        display_question()
    else:
        print("Very good!")

display_question()
