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.

Thanks for this great course Chris! Made working with modules and packages much clearer. Now I need to watch it again.

Thanks Chris! Python modules and packages concepts are much clearer now.

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!

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!

Great course. Brought to order and systematized all I have learned just googling things quickly. Thank you!

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.

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