在Python的程序开发中，为了防止源代码泄露或被恶意篡改，我们经常需要对代码进行加密或保护。在上一节教程中，已经介绍了py文件如何批量加密成二进制的pyd文件，并通过使用import语句加载pyd文件模块，使代码模块得到保密。对于Tkinter程序（Python的GUI应用程序），同样可以加密成二进制的pyd文件，再通过使用import语句加载pyd文件模块。
Tkinter程序加密步骤
步骤1：准备Tkinter程序文件
首先，我们使用Python的Tkinter库来创建一个扫雷（Mine Sweeper）游戏。扫雷游戏是一款经典的益智游戏，玩家通过逻辑推理排除地雷，核心规则是通过数字提示判断周围雷区分布。在游戏中，当我们点击一个未知方块时，如果它是地雷，则游戏结束并显示所有地雷隐藏的位置。如果不是地雷，它会显示周围地雷的数量。我们可以使用鼠标右键标记我们认为是地雷的方块。游戏中有“重新开始”和“退出”两个按钮。通过颜色区分已扫地雷与未知方块。游戏效果图如下所示：
扫雷游戏完整代码如下所示：
from tkinter import *
import random
def showapp():
class Mineclear:
def __init__(self, rows, cols, mines):
self.rows = rows
self.cols = cols
self.mines = mines
self.app = Tk()
self.app.title("经典扫雷游戏")
self.app.geometry("288x400")
self.app.resizable(False, False)
self.app.update_idletasks()
window_width = self.app.winfo_width()
window_height = self.app.winfo_height()
screen_width = self.app.winfo_screenwidth()
screen_height = self.app.winfo_screenheight()
x = (screen_width - window_width) // 2
y = (screen_height - window_height) // 2
self.app.geometry(f"{window_width}x{window_height}+{x}+{y}")
self.buttons = [[None for _ in range(cols)] for _ in range(rows)]
self.design()
self.layout()
self.begin()

rows = 12
cols = 12
mines = 18
mine_game = Mineclear(rows, cols, mines)
mine_game.app.mainloop()
if __name__ == '__main__':
showapp()
我们把以上游戏代码保存为minesweeper.py文件，再通过上一节教程中介绍的方法，把minesweeper.py文件编译成minesweeper.pyd文件。
步骤2：为Tkinter程序提供运行文件
在Pyhint编辑器的文件夹内，把上面已编译的minesweeper.pyd文件保存到“Pyhint\Learn-Python\test”文件夹内，在“Pyhint\Learn-Python\test”文件夹内再创建一个main.py运行脚本文件，main.py文件代码如下所示：
main.py：
from minesweeper import showapp
mygames = showapp()
最后，通过Pyhint编辑器运行“Pyhint\Learn-Python\test”文件夹内的main.py文件，就可以运行扫雷游戏程序，这个方法可以有效实现Tkinter程序的加密或保护，以防止源代码泄露。
