A Full-Length Machine Learning Course in Python for Free

One of the most popular Machine-Leaning course is Andrew Ng's machine learning course in Coursera offered by Stanford University. I tried a few other machine learning courses before but I thought he is the best to break the concepts into pieces make them very understandable. But I think, there is just only one problem. That is, all the assignments and instructions are in Matlab. I am a Python user and did not want to learn Matlab.
