How not to become a Python-developer

What does the track to learn programming in Python from scratch look like? Where to start? What to focus on? How not to lose interest?

For six months I have been looking for answers to these questions, carefully researching the subject area. I found a lot of useful tips. Especially in the article by Vasily Bolshakov and Hexlet . But I lacked structure. Knowledge grew from all sides and turned into a bunch. To structure the learning process and assess its scope, I put together a plan.

When composing the program, I was guided by the philosophy of Tim Peters, who formulated The Zen of Python :

Simple is better than difficult
Difficult is better than confusing
Practicality is more important than perfection
Mistakes should never be silenced.
Now is better than never ...

Plan of the education

I am a beginner in development, so my journey started from the very beginning. At the moment I have passed about half. Most likely, I missed something, I didn’t figure it out properly. If you want to share experiences or advice, feel free to write in the comments. It is also important to note that the learning track is designed for Mac OS users. Other platforms have their own characteristics, we will not talk about them.

The program is divided into steps. The sequence is conditional. Within each step, there are tasks with an asterisk — desirable, but optional.

1. Understand why you need it

I have two goals: quickly analyze data and create prototypes for testing ideas. For this, it is enough for me to know several suitable libraries, understand someone else's code and write my own a little. What is your goal?
