Free From MIT: Intro to Computational Thinking and Data Science - KDnuggets

It aims to provide students with an understanding of the role computation can play in solving problems and to help students, regardless of their major, feel justifiably confident of their ability to write small programs that allow them to accomplish useful goals. The class uses the Python 3.5 programming language. The Fall 2016 iteration of this course is taught by Eric Grimson, John Guttag, and Ana Bell. The course is taught using only Python as the implementation programming language.
