In this course, you’ll learn about Python modules and Python packages, two mechanisms that facilitate modular programming.

Modular programming is the process of breaking a large, unwieldy programming task into separate, smaller, more manageable subtasks or modules. Individual modules can then be put together like building blocks to create a larger application.

Learn how to write and import modules so you can optimize the structure of your own programs and make them easier to maintain and grow.

I have referred back to the article version of this course countless times but these videos worked well to give me a deeper understanding and solidify the knowledge. Well done Chris!

Really enjoyed this course Chris! This is a great example on how a basic/introductory course should be presented. Thanks!

Great course Chris. I had a general understanding of packages and modules, but I gained a deeper insight into sub-packages and dot notation.

On to the next course.

Thanks, Patrick.

Hi Chris,

This was a great course. It really exposed me to more of the nuts & bolts of Python. This is something I am struggling to understand, working on my Django project. I really appreciate your sharp quick and concise approach to the subject of OOP in Python Modules and Packages-even though I found it necessary to started and stopped the video many…times to practice and make sure I was on the same page - it really worked!

bphthon, very nice! This was my first time using it and I really like it. I had an issue installing it to macOS Mojave (10.14.6) but found a solution here, just incase anyone else has this issue.

Thank you - Well done!

I dunno how you managed to provide a thorough tutorial on exactly what I needed, two days before I needed it, but I certainly appreciate it. Thank you!
