python - tkinter - 未定义按钮中的函数调用
问题描述
我迷路了！我正在尝试编写某种与原始游戏相比有一些变化的二十一点游戏。如果您注意到在代码的末尾，我创建了一个名为 restart_button 的按钮。
他调用的函数是reset_game。当我尝试运行代码时，我收到错误消息 - NameError: name 'reset_game' is not defined
你们知道我该如何解决吗？提前致谢
附言。我在 2 个月前开始编码，所以请不要对我不那么漂亮的代码生气。

window.mainloop()
解决方案
restart_button看不到里面main()。main()由于某种原因，您在函数中定义了一堆函数，包括reset_game，因此不在范围内的任何内容main()都看不到这些函数。解决方案是将函数移到main().
