Hello,

I am an electronic engineer, I have mostly been using python for quick test of algorithms, or for having a easy quick way to communicate embedded systems to PC.

I would like to learn a little more of python, I am most of the learn by doing rather than read books.

Most of my programs have been scripts on a single file, at most I use def to create functions.

I would like to learn how and why should I use OOP approach and classes, so any pointers would help.

Since I learned the basics of programming, I have always tried to learn about OOP and their approach, but I really find most tutorials as not practical.

​

They are like, lets make class, animal and then lets make sub class lion that inherits from animal, etc...
