Chinese Idiom Chain Game Implemented with Python Tkinter

Idiom Chain is an educational game that helps learn Chinese idioms while having fun.

The following Python code implements a Tkinter GUI for the game, including functions to load idioms from a JSON file, validate idioms, provide hints, and manage game flow.

import tkinter as tk
from tkinter import messagebox
import random
import json
import re
# 成语库
idiom_url = 'idiom.json'

def idioms_continue(guess):
    matching_idioms = []
    with open(idiom_url, 'r', encoding='utf-8') as file:
        s = json.load(file)
    for i in s:
        if i['word'][0] == guess[-1]:
            matching_idioms.append(i['word'])
    return matching_idioms[0] if matching_idioms else False

def idioms_start(user_input=None):
    # 如果没有用户输入，就随机选择一个成语开始
    if user_input:
        return user_input
    with open(idiom_url, 'r', encoding='utf-8') as file:
        s = json.load(file)
    return random.choice(s)['word']

def is_idiom(s):
    pattern = re.compile(r'^[\u4e00-\u9fa5]+$')
    return bool(pattern.match(s)) and 4 <= len(s) <= 8

    root.mainloop()

    main()

The code imports tkinter for GUI creation, messagebox for dialogs, random for selecting idioms, json for reading the idiom database, and re for validating idiom format. It defines the idiom data path, helper functions for finding continuation idioms, starting the game, and checking idiom validity. The IdiomGameGUI class builds the interface, handles user input, enforces game rules, provides hints, and allows quitting. The main function launches the application.
