Introduction to Python Exceptions

Darren Jones 3 Lessons 13m basics python

A Python program terminates as soon as it encounters an error. In Python, an error can be a syntax error or an exception. In this course, you will see what an exception is and how it differs from a syntax error. After that, you will learn about raising exceptions and making assertions. Then, you’ll finish with a demonstration of the try and except block.

Thank you so much Darren Jones: I believe in learning basics to the core would be the first best step we have to do on any technology. once we know it we can crack it. I am an Automation Developer working on infrastructure layer required more Error handlings and exceptions on case to case. Thanks for making me easily understand this tricky concept in Python. I will start from here.

This is a good lesson and I understood the material well once finished. I had been watching/reading other courses on this subject (try, except, assert) and was still not clear on how to use them. This course was way easier to understand! Very well structured and presented. Thanks for your efforts!

Great class, albeit, very short, even though it seemed to cover all of the features of Exceptions in an extremely clear & succinct way. I look forward to seeing more courses by Darren.
