Do you know how to log in Python? Maybe you used a logger in another languages. But how about in Python?

It’s simple, so follow me and let’s go. The first step is to import logging:

import logging

Now, log a message:

logging.warning('this a message of warning level')
logging.info('this a message of info level') #but this message will not show up, because default level is warning

By default, only warning messages are shown.

Additionally, to put messages inside a file, just add the following:

logging.basicConfig(filename='test.log', filemode='w', level=logging.DEBUG)#put message inside a file

and that’s all folks!

If you have any doubts, problems or suggestions, just leave a message.
