With so many glowing reviews, I don't think mine matters, but here it is anyway: This course is amazing.
This course is so amazing that a) I realized I threw away way too much money on a different "introduction to python" course that had live instructors and one-on-one access to mentors because this class was free and far more beneficial; and b) when I'm done writing this review, I'm going to sign up for the whole Coursera Python for Everybody specialization.
The Python playground is amazing, but it isn't even necessary because the instructor provides such great material for getting Python installed and running on your computer (with windows, mac, and linux instructions), even a complete beginner would be able to follow the instructions and make a functioning script in no time. But the playground is just a lot of fun to play with, and makes tinkering as a beginner super easy.
I spent one whole day and finished the entire Getting Started with Python course (auditing, no quizzes), and learned more than I learned in the first 4 weeks of a 6 week paid course. Dr. Chuck is GOOD at what he does. He presents material in a very down-to-earth manner in clear, plain language that's technical, but not over my head. I have very little experience with programming, and know the basics of computers and computing, but even the introduction to hardware architecture was fascinating and I learned more about hardware than I expected. I felt a lot more prepared to dive into programming after that lecture.
The amazing thing is that so much is crammed into such short lectures, and yet the material is still accessible.
Speaking of accessibility: the lectures have captions AND interactive transcripts. The audio is crisp and clear, as is the video-- without background noise or distractions. The dedication to accessibility has blown me away and is another big reason I plan to support Coursera by paying for the specialization path.
