Question

我正在尝试创建一个数独谜题，所以我想出了下面的这个python代码，用于打印一个字典，其键来自Btns列表，但是在运行时代码不能完成任务，也可以不要给出任何错误信息。我需要帮助解释问题可能是什么以及如何解决它。

    from random import randint

    Btns = ['A11', 'A12', 'A13', 'A21', 'A22', 'A23', 'A31', 'A32', 'A33',

可能存在以下情况：所有列表中都没有1到9的数字：

A11：1，A12：2，A13：3，A21：4，A22：5，A23：6，A31：7，A32：8，A33：9

B15：6，B25：2，B35：1

D51：3，D52：4，D53：5

E44：7，E45：8，E46：9

现在可以在E55中填写什么？没有什么可能，而循环将被卡住。

循环没有完成它的任务
