In many Python programming situations, at some point, as your application grows you want to start storing logs in a file. Since the very early days ( about my Python experience here ) that was the case for me. In this post, I’ll share my ideas for the “How Do I Store Python Logs In A File?” question.

How Do I Store Python Logs In A File?

One way to store these Python logs in a file so you can look at them later is to write them to a file using a built-in logging module. 

Here’s an example of how to use the logging module to store logs in a file in Python:

import logging

# Configure the logging module to use a file
logging.basicConfig(filename='example.log', level=logging.DEBUG)

# Write some log messages
logging.debug('This is a debug message')
logging.info('This is an info message')
logging.warning('This is a warning message')
logging.error('This is an error message')
logging.critical('This is a critical message')

In this example, the basicConfig() function is used to configure the logging module to write logs to a file named ‘example.log’.

The level argument is set to logging.DEBUG which means that all log messages, including debug, info, warning, error, and critical messages, will be written to the file.

Then the code uses different logging levels debug(), info(), warning(), error() and critical() to write different log messages.

When you run this code, it will create a new file called ‘example.log’ in the same directory as your script, and the log messages will be written to it.

Obviously, this is a very simplified version of logging in Python, I’ll get into more details and other examples in the following sections of this post.
