Python : clear a log file

问题

I develop a client-server application and I have log in the server, so I use the logging module. I would like to create a command in the server to clear the file.

I have test with os.remove() but after, the log doesn't work.

Do you have an idea?

Thanks.

回答1:

It might be better to truncate the file instead of removing it. The easiest solution is to reopen the file for writing from your clearing function and close it:

with open('yourlog.log', 'w'):
    pass
