如何实现问答游戏的Entry题目切换、答错退出及题库文件读取？

Hey there! Let's tackle your three main game requirements one by one—switching to the next question when you get an answer right, exiting immediately on a wrong answer, and loading questions from a text file instead of hardcoding them. I'll walk you through each fix with modified code you can drop right into your project.

1. Auto-Switch Questions on Correct Answers + Exit on Wrong Ones #

First, we need to add click handlers to your answer buttons so they can verify if the selected answer is correct. We'll also track your progress through the question list to move to the next question automatically when you get one right.

Key Tweaks: #

• Organize all questions/options/answers into a list of dictionaries (this also makes it easier to load from a file later).
• Add a current_question_idx variable to keep track of which question you're on.
• Write a check_answer function that handles correct/wrong logic, updates the UI, or exits the game.
• Bind this function to each answer button so clicking triggers the check.

2. Load Questions from a Text File #

Instead of hardcoding every question, we'll use a simple text file format. Here's how to set it up:

Question File (questions.txt) Format: #

Each line represents one question, split by pipes (|):

What's the capital of Nigeria|Mongoria|Cairo|Accra|Abuja|Abuja
Which one of the colors can be found in the US National Flag|Green|Red|Orange|Yellow|Red
What is 5000 x 110|55,110|56,100|50,000|55,000|55,000
Whitney Houston died in which year|2013|2010|2012|2011|2012
How many countries are there in Africa|32|43|45|30|45

(Fixed a typo "Yelow" to "Yellow" in the second question for accuracy)

Loading Function: #

We'll add a load_questions function that reads this file and converts each line into a structured question entry.

Full Modified Code #

Here's the complete code with all three requirements implemented:

from tkinter import *
import tkinter as tk
import pygame as py
from PIL import ImageTk, Image
import time, random, sys
from pygame.locals import *

py.init()
py.mixer.init()

root = Tk()
root.title("Who Wants To Be A Millionaire")
root.geometry('1352x625+0+0')  # Fixed syntax error here (removed the equals sign)
root.configure(background='black')

abc = Frame(root, bg='black')
abc.grid()
abc1 = Frame(root, bg='black', bd=20, width=900, height=600)
abc1.grid(row=0, column=0)
abc2 = Frame(root, bg='black', bd=20, width=452, height=600)
abc2.grid(row=0, column=1)
abc1a = Frame(abc1, bg='black', bd=20, width=900, padx=110, height=200)
abc1a.grid(row=0, column=0)
abc1b = Frame(abc1, bg='black', bd=20, width=900, height=200)
abc1b.grid(row=1, column=0)
abc1c = Frame(abc1, bg='black', bd=20, width=900, height=200)
abc1c.grid(row=2, column=0)

            line = line.strip()
            if not line:
                continue
            parts = line.split('|')
            if len(parts) != 6:
                print(f"Skipping invalid line: {line}")
                continue
            question_text, opt1, opt2, opt3, opt4, correct_ans = parts
            questions.append({
                'question': question_text,

    if current_question_idx >= len(questions):
        textQues.delete(0, END)
        textQues.insert(0, "Congratulations! You won!")
        # Disable all buttons once the game ends
        text_option1.config(state=DISABLED)
        text_option2.config(state=DISABLED)
        text_option3.config(state=DISABLED)
        text_option4.config(state=DISABLED)
        return
    
    current_q = questions[current_question_idx]
    question1.set(current_q['question'])

        current_question_idx += 1
        update_question()
    else:
        # Exit immediately on wrong answer
        root.destroy()
        sys.exit()

Quick Notes: #

• Make sure questions.txt is saved in the same folder as your Python script, using the format shared above.
• Fixed a small syntax error in your original code: root.geometry=('1352x625+0+0') became root.geometry('1352x625+0+0') (removed the incorrect equals sign).
• When you answer all questions correctly, the game shows a victory message and disables buttons.
• Clicking a wrong answer closes the window and exits the program immediately.
