I want code changes to take effect immediately during development. How can I detect changed files and reload them in the running Python (2.7) application?

阅读完"Ivo van der Wijk"链接的页面后，我认为最好在代码更改时重新启动Web应用程序，就像Django一样.因此，实际的问题是:如何监视文件修改?

After reading the pages linked by 'Ivo van der Wijk', I think it would be best to restart the web application when code changes - like Django does. So the actual question is: How to monitor file modifications?

This question has been asked a number of times

您可以为此使用reload(module)，但要注意讨厌的副作用.例如，现有代码将基于原始代码，不会神奇地添加新的属性或基类.

You can use reload(module) for this, but beware of nasty side effects. For example, existing code will be based on the original code, it will not magically get new attributes or baseclasses added.
