6.00x is an introduction to using computation to solve real problems. The course is aimed at students with little or no prior programming experience who have a desire (or at least a need) to understand computational approaches to problem solving.

This is not a beginner level course. You should have a decent understanding of programing or be prepared to spend a significant amount of time Python tutorials.
Decent MOOC which does teach you the basics of programming.
However, the hands-on programming assignment only requires editing small little functions, and thus do not yield the same sense of achievement as other MOOCs where your code actually does something significant.
Having dived into CS work without a foundation in theory, this course gave me a nice background. Would recommend to anyone looking to gain understanding/get practice in different data structures, especially in Python.
