Logging in Python Quiz - Real Python
Briefly

Logging is a very useful tool in a programmer's toolbox.
Logs provide developers with an extra set of eyes that are constantly looking at the flow an application is going through.
They can store information, like which user or IP accessed the application.
If an error occurs, then they can provide more insights than a stack trace by telling you what the state of the program was before it arrived and the line of code where the error occurred.
