🐍 Your Journey to Fluent Python

👋 Welcome to the thrilling journey to Python fluency!

[!NOTE] Initially this repository was supposed to be a Senior Developer Roadmap and had to include not only Python but DB, AWS, Linux and BE Frameworks. That was not the best approach to do and cover everything at once, so I decided to focus only on Python and during the process this book has been created! I worked on it alone, almost 1.5 years, and hope that you will like it. In the future I have plans to colaborate with a major UK publisher to create the second version of this book. If you could provide any feedback, this would be extremely valuable. Attaching PDF version for free to improve your learning experience!

👤 Introduction

My name is Yehor, and I'm the CTO and co-founder of Swetrix, a privacy-focused analytics platform. Additionally, I hold a Software Engineer position at a company based in Oxford, United Kingdom 🇬🇧.

After years of studying programming, I've reached a solid level of proficiency, mainly through reading books and exploring different courses.

I've found that many books in the programming world lack practical relevance and don’t give the knowledge to actually build real software. They're informative but don’t have interactivity and engagement with a learner at all.

That's why I am excited to introduce a revolutionary approach to education and interaction with books.

This isn't just another book to read. It's a comprehensive guide that will walk you through every step of your learning journey, providing interactive experiences and personalised support along the way.

In order to interact with me, you have 2 options:

1. Open a PR and submit your homework/questions, and I will review it on Github directly.
2. Join the Discord server where you can submit your H/W for my personal review through tickets instead, ask general questions about the topic you are struggling with, and integrate into our Python society to excel your knowledge and skills together.

In case you have any questions or would like to contact me directly, just do it!
