How to create a log file in Python script?

You can use the logging module to accomplish this.

import logging

At the very easiest level, it will be set up like this:

logging.basicConfig(filename="mytechmint-logfile.log", level=logging.INFO)

There are a number of different levels that you can use to write to the file, such as:

logging.info('your text goes here')
logging.error('your text goes here')
logging.debug('your text goes here')
