Python User Defined Function

This video shows how to implement a user defined function that has two input parameters and a return value.

I think it's weird these videos aren't more popular, this is genuinely educational.

Grateful for this video which is great. Very clear elaboration that allows me to conceptualize the structure of user-defined function,

John, You have just broken down the most important party of python learning into nice chunks an idiot can understand.  Thanks and well done.

Nothing to add, except that in modern software development, presumably even if not OOAD, the unit tests would likely be retained and run whenever someone makes changes to a module. Some people act like unit testing implies classes and objects, others would say, no, it just implies test code somewhere that gets run.

Thank you so much for this video, now I really understand! You have a really terrific method of teaching. I'll be watching all the Python vids since I'm trying to learn it and I'm a beginner to programming. Is there a specific video on how to read/write and create text files?
