ℹ️ ABOUT THIS VIDEO:
In this video, I'll go over the best practices for error and exception handling in Python. In Python programming, you'll come across errors and exceptions in many places. This includes error handling in requests, flask, for loops and IO related such as file not found. Understanding how to handle errors in Python starts with understanding try/except/else/finally so we go over those in this video. Errors are used interchangeably with exceptions in Python so we will go over analysing exceptions in Python, getting the exception types, stack traces and tracebacks.

This is a jam packed tutorial and error handling is an essential topic for every Python programmer.

Python is the world's most popular programming language in 2020. Python is a great programming language that's used by the likes of Google, Facebook, Twitter, Quora and pretty much every big tech company you can name. It's used everywhere, whether it's in competitive programming, coding interviews, areas of data science, machine learning and algorithmic trading. Follow me as I continue to produce Python tutorials that will help you become a rockstar programmer.

Thankyou, my python instructor threw me in to a project (that required caching KeyErrors) without properly explaining this, you made this concept very clear!

MadDogCat

Thanks for this detailed explanation. This was exactly what I was looking for (including "Finally:") :😜

I am a basic learner in python but with this video I learn a lot thank you 🙇🙇🙇😊

sorry for being spiteful, but in my opinion try statement should only be used for nondeterministic exceptions, i.e. the ones that you cannot anticipate in advance, usually while accessing external systems like files or databases, and not for deterministic exceptions. missing key can be anticipated in advance. therefore you should use an if statement here instead.

The link is dead for me to download the book, imdad.

I think this was more an introduction to exceptions in python (which was nicely done) than a best practice course about them. As you say yourself you do not know how to use "finally" in useful cases and so on (this is ok, but the tittle is misleading) . The tittle and thumbnail could be changed to better reflect this.
Nice video nonetheless
