为什么我不断在python中收到这个大错误.追溯(最近一次呼叫过去)…和AttributeError
作者：互联网
我一直在学习python,并从互联网上获取不同的东西,并将它们全部放入我正在制作的游戏中：“您醒了……”这是一个基于文本的assci RPG(滚动游戏).它一直起作用,直到出现此错误：

解决方法:
您在main.py中的init()调用必须位于if __name__ ==’__main__’：块中,并且您不应该自己设置__name__-Python将自动执行此操作.
否则,循环导入将导致在调用init()之前无法正确导入辅助程序.现在的顺序是这样的：
>您运行main.py,这将开始评估main.py.
> main.py中的导入帮助器行将开始评估helper.py.
> helper.py中的import main行开始了对main.py的另一次评估,因为先前尚未导入main模块.
> main.py的第二次评估中的import helper行将导入在#2开始导入helper时创建的现有helper对象,因此这不会创建无限循环-但是现有的helper对象尚未完全加载;它仍在等待主要进口商品解决.
> main的第二次评估命中了main.py底部的init()调用,该调用尝试运行init()-但是helper仍未完成加载,因此helper.py中的way_out_quest函数尚未完成尚未评估,因此未定义.
通常,最好首先避免循环导入-这样就不必担心此类问题.
