我有一个关于代码执行的一般问题。我有一个案例，相同的代码在shell中完美执行，并在Jupiter中有一些问题。
在Jupyter Notebook中，它往往会停止，通常是在循环开始时或用户输入之前。什么都没发生，但内核很忙。代码的相同部分有时有效，有时则无效。
程序非常简单，因此不应成为问题。你遇到过类似的问题吗？是不是因为我没有将代码分成几个单元格？提前谢谢了！
编辑：我添加了完整的代码，因为我没有设法在较小的样本上重新创建问题。基本上问题出现在游戏开始时应该执行hit_or_stand或者在repeat_game（）函数级别。# import

拆分单元格中的代码与问题无关。使用不同的单元格，因此您不会一次又一次地运行相同的代码。笔记本和外壳有一些小差异，但基本思路是一样的。你应该分享笔记本代码，所以，我可以帮助你解决问题。
