多次从文件中运行python文件

Question

基本上，我正在制作一个塔防御游戏，我有一个名为enemy.py的python文件，里面有圆形，还有一个名为main.py的文件，它是圆形屏幕的末尾。我希望main.py在每一轮结束后执行enemy.py，但是它给了我第二次错误。我使用导入函数打开其他文件。另外，能不能有人帮我做，这样错误就没那么大了，我很困惑！

ImportError: No module named 'enemy.py'; 'enemy' is not a package

Answer 1

首先删除.py文件后缀。语法只是：

import enemy

这将运行enemy.py中的所有代码(假定enemy.py位于Python已知的路径中)。

如果您想重复这个过程，要使用的命令是：

reload(enemy)

不过，这并不是使用模块的好方法。最好是在敌人内部创建一个函数，并直接调用它：

import enemy
enemy.enemy()
