Performing vectorized operations using scientific computing libraries like NumPy.Handling multi-dimensional arrays, indexing, slicing, transposing, broadcasting and pseudorandom number generation using NumPy.Writing Python scripts to extract, format, and store data into files or back to databases.Common data structures (data types, lists, dictionaries, sets, tuples), writing functions, logic, control flow, searching and sorting algorithms, object-oriented programming, and working with external libraries.Topics and libraries to know for data science: Hands down a good pick for developing end-to-end projects.
I personally prefer Python over any other language because of its versatility how relatively easy it is to learn. I am going to focus on technical data jobs that require expertise in at least one programming language. Most data roles are programming-based, except for a few like business intelligence, market analysis, product analyst, and others.
Essential Programming Skills for Data Science and Machine Learning Let's go through these essential skills in a bit more detail to see what you need to learn to get into Data Science and Machine Learning. Here is what Google recommends that you do before taking an ML course: Google's recommended Python skills for Data Science and Machine Learning Google's recommended Math and Statistics skills for ML and DS ( Source) If you go through the prerequisites or pre-work of any ML/DS course, you’ll find a combination of programming, math, and statistics. The Three Pillars of Data Science and Machine Learning Source: So in this article, I'll lay out some of the first steps you should take to learn Data Science or Machine Learning. But that book is a bit too technical and math heavy for many. You can find answers to a lot of these questions in the book Deep Learning by Ian Goodfellow and Yoshua Bengio.

What should you do after learning how to code? Are there topics that help you strengthen your foundations for data science?.Python programming was the only branch that had a number of really good courses but it ends right there for beginners.Ī few important questions on foundational data science struck me: Many people found the roadmap useful, my article got translated into different languages, and a large number of folks thanked me for publishing it.Įverything was good until a few developers pointed out that there are too many resources and many of them are expensive. At the start of this year, I published a mind map on the Data Science learning roadmap (shown below).
