A Complete Data Science Roadmap in 2021

If you want to learn data science from scratch, the first thing you need to do is learn how to code. Pick a programming language (either Python or R), and start learning. I suggest starting out with Python because it is more widely used than R. It is also more general and highly flexible, and you will be able to make the transition to different domains (data analytics, web development) if you have Python knowledge. This DataCamp course will take you through exercises and teach you how to code in Python. What will you learn in this course?
