It is 2021 already, and still, we cannot stop hyping over Python as a programming language. The popularity of Python as a general-purpose language in various fields like competitive programming, web development, web scraping, data science, machine learning, and what not has made it a superpower language to learn this 2021.

Therefore this blog is dedicated to your Python learning journey with a well-defined roadmap designed especially for beginners and intermediate Pythonistas.

We’ll begin with a ‘Warm Up’ stage where we’ll revisit the programming fundamentals and your version control knowledge of Git and GitHub along with some Command-Line basics. Next up we’ll start with the basics and proceed towards programming paradigms to the most important libraries in Python.

Every stage comprises a few sub-stages for which we have set no time bounds, but small tasks to get you going to the next learning stage. We sincerely hope that the listed tutorials give you the best knowledge of Python! Let’s get going.
