Python Exceptions: try.. except.. else.. finally

Erik from Python Land — Fri, 31 Dec 2021 11:58:00 +0000

Python exception handling is the process of identifying and responding to errors in a program. In other words, it is a way to deal with errors that might occur in your program.

In my latest article on exception handling at Python Land, you will learn how to handle errors in Python by using the try and except keywords. You’ll also learn how to create custom exceptions.

I'd love to get feedback on the article. I tried my best to structure it in such a way that readers really get to understand how this stuff works. But I'm far from perfect and always trying to improve, so don't hesitate to drop a comment here or on Python Land.
