如何使用子功能重新启动Python脚本

Question

I have a massive Python script that needs to be restarted automatically when it breaks. When I try a standard approach by wrapping the script into a function and then calling it via while True , I get this error:

SyntaxError: unqualified exec is not allowed in function 'wrappedFunc' because it contains a nested function with free variables

As I understand, this is due to the fact that my main script has sub functions. Can I still do it somehow via Python or should this be done in Windows via a batch file?

Answer 1

The error is related to using the exec keyword inside a function that has subfunctions. Python needs you to explicitly determine which scope the exec will use to run in this case.

Answer 2

exec command: execfile('file.py') . Insecure and kind of hack hacky. Avoid wherever possible. Spawn a shell process: os.system('python file.py') . Use when desperate.

PS: i haven't tried it to invoke/run same file
