试图让我的python代码询问一定数量的问题，然后停止 [英] Trying to get my python code to ask a set number of questions and then stop

问题描述

目前，该代码运行着无数问题，并且除非您选择我包含的退出选项，否则永远不会停止，但是我想摆脱它，因此它仅取决于用户输入的问题数量.我知道我需要一会儿循环，但是我不知道如何正确安装它.请帮忙，这里是代码

At the moment the code runs for an infinite amount of questions and never stops unless you select the exit option I included in but I want to get rid of it so it solely relies on the amount of questions the user inputs. I know I need a while loops but I don't know how to install it properly. Please help here is the code

   import random

def display_intro():
    title = "** A Simple Math Quiz **"
    print("*" * len(title))
    print(title)
    print("*" * len(title))


def display_menu():
    print("Choose your difficulty !")
    menu_list = ["1. Easy", "2. Hard", "3. Spicy", "4. Exit"]
    print(menu_list[0])
    print(menu_list[1])
    print(menu_list[2])
    print(menu_list[3])

def get_user_input():
    user_input = int(input("Enter your choice: "))
    while user_input > 4 or user_input <= 0:
        print("Invalid menu option.")
        user_input = int(input("Please try again: "))
    else:
        return user_input

def num_questions():
   total_questions = int(input("How many questions would you like?: "))
    while total_questions >= 0 and total_questions < 100:
        print("Lets Go!")
        break

        count = check_solution(user_solution, solution, count)
        return count

def display_result(total, correct):
    if total > 0:
        result = correct / total
        percentage = round((result * 100), 2)
    if total == 0:
        percentage = 0
    print("You answered", total, "questions with", correct, "correct.")
    print("Your score is ", percentage, "%. Thank you.", sep = "")

    while option != 4:
        total = total + 1
        correct = menu_option(option, correct)
        option = get_user_input()

    print("Exit the quiz.")
    display_result(total, correct)

推荐答案

这是解决方案:

import random

total_questions = 0 # make it global

def display_intro():
    title = "** A Simple Math Quiz **"
    print("*" * len(title))
    print(title)
    print("*" * len(title))


def display_menu():
    print("Choose your difficulty !")
    menu_list = ["1. Easy", "2. Hard", "3. Spicy", "4. Exit"]
    print(menu_list[0])
    print(menu_list[1])
    print(menu_list[2])
    print(menu_list[3])

def get_user_input():
    user_input = int(input("Enter your choice: "))
    while user_input > 4 or user_input <= 0:

    else:
        return user_input
