The list of free and non-free resources and courses for quick start in Machine Learning and Data Science. I built this list by searching in Google and taking references from articles about ML and data science. It is updated from time to time and you also can suggest one in comments.

The discipline can be divided to the following areas:

- Mathematics, applied statistics and the probability theory
- Programming (R or Python in particular) and working with tools for data analysis
- Machine learning methods including deep learning

Courses and resource for mathematics and statistics are skipped because this subject is covered with courses for R and Python.

# Programming

According to the poll results of KDnuggets, R, Python Duel As Top Analytics, Data Science software two languages are the most popular in the discipline: R and Python. This article describes the difference between two.

Below is the list of resources and courses for both of them.
