Python 如何在Windows中使用Popen调用外部.py脚本并等待其完成,python,windows,Python,Windows,您是否尝试过调用外部zip.py脚本来执行此反馈？我的CGITB没有显示任何错误消息。它只是没有调用external.py脚本来工作。它只是简单地跳过去喷涌。如果您能帮助我在feedback.py中调用此zip.py，我将不胜感激问候。大卫 #********************************************************************** # Description: # Zips the contents of a folder. # Par

zip（）
```
是Python中的内置函数。因此，使用
```
zip
```
作为变量名是一种不好的做法<代码>邮政编码可用于代替
```
execfile（）
```
函数读取并执行Python脚本
可能您实际上只需要在feedback.py中导入zip文件，而不需要导入execfile（）
