python - 有没有办法不在我的代码中使用全局变量？

问题描述

我对 Python 比较陌生，所以请忍受我的代码效率低下。这是我的第一个 Tkinter 应用程序之一，它非常简单。这是一个密码猜谜游戏，用户尝试猜测随机生成的 4 位密码。该代码当前打印随机生成的数字，以便更容易查看代码是否有效。但是有没有办法在这段代码中不使用全局变量。此外，如果有人告诉我如何使我的代码高效，那将会很有帮助。提前致谢。代码：

import random
import tkinter as tk

number_of_tries = 0


def tries():
    global number_of_tries
    number_of_tries += 1
    comment.configure(state="normal")
    comment.delete(0, "end")
    comment.insert(0, "Not quite! Keep trying!")
    comment.configure(state="disabled")
    if str(guess) == str(random_number):
        comment.configure(state="normal")
        comment.delete(0, "end")
        comment.insert(0, "You guessed it in " + str(number_of_tries) + " tries!")
        comment.configure(state="disabled")
        guess_entry.configure(state="disabled")
        go.configure(state="disabled")


def character_check():
    global guess
    guess = guess_entry.get()
    if len(guess) != 4:
        comment.configure(state="normal")
        comment.delete(0, "end")
        comment.insert(0, "Guess must be 4 digits! ")
        comment.configure(state="disabled")
    else:
        for char in guess:
            if char.isalpha():
                comment.configure(state="normal")
                comment.delete(0, "end")
                comment.insert(0, "Guess must only include integers! ")
