python用gui做一个剪刀石头布游戏

好的，我们可以使用Python自带的GUI库Tkinter来实现这个剪刀石头布小游戏。

首先，我们需要导入Tkinter库和random库：

import tkinter as tk
import random

然后，我们需要定义一个函数来处理用户点击按钮的事件，并随机生成电脑的选择：

def play_game(player_choice):
    computer_choice = random.choice(["剪刀", "石头", "布"])

接下来，我们需要根据用户和电脑的选择来判断胜负，并给出相应的提示：

    if player_choice == computer_choice:
        result_label.config(text="平局！")
    elif player_choice == "剪刀" and computer_choice == "石头":
        result_label.config(text="你输了！")
    elif player_choice == "石头" and computer_choice == "布":
        result_label.config(text="你输了！")
    elif player_choice == "布" and computer_choice == "剪刀":
        result_label.config(text="你输了！")
    else:
        result_label.config(text="你赢了！")

在主函数中，我们需要创建一个窗口，并添加一些控件，如标签、按钮等：

window = tk.Tk()
window.title("剪刀石头布游戏")

scissors_button = tk.Button(window, text="剪刀", command=lambda: play_game("剪刀"))
scissors_button.pack(side="left")

rock_button = tk.Button(window, text="石头", command=lambda: play_game("石头"))
rock_button.pack(side="left")

paper_button = tk.Button(window, text="布", command=lambda: play_game("布"))
paper_button.pack(side="left")

result_label = tk.Label(window, text="")
result_label.pack()

window.mainloop()

完整代码如下：

import tkinter as tk
import random

def play_game(player_choice):
    computer_choice = random.choice(["剪刀", "石头", "布"])
    if player_choice == computer_choice:
        result_label.config(text="平局！")
    elif player_choice == "剪刀" and computer_choice == "石头":
        result_label.config(text="你输了！")
    elif player_choice == "石头" and computer_choice == "布":
        result_label.config(text="你输了！")
    elif player_choice == "布" and computer_choice == "剪刀":
        result_label.config(text="你输了！")
    else:
        result_label.config(text="你赢了！")

window = tk.Tk()
window.title("剪刀石头布游戏")

scissors_button = tk.Button(window, text="剪刀", command=lambda: play_game("剪刀"))
scissors_button.pack(side="left")

rock_button = tk.Button(window, text="石头", command=lambda: play_game("石头"))
rock_button.pack(side="left")

paper_button = tk.Button(window, text="布", command=lambda: play_game("布"))
paper_button.pack(side="left")

result_label = tk.Label(window, text="")
result_label.pack()

window.mainloop()

运行程序，你就可以在窗口中玩剪刀石头布小游戏了。
