Andrew's new deep learning courses (http://www.deeplearning.ai) all use Python. When I last spoke to him he was no longer enthusiastic about using Octave/Matlab for teaching.
There is some truth to Octave having a faster turnaround than Python, if you're new to programming. I feel like with Deep Learning you really have to bite the bullet, but his courses are just fine with Octave/Matlab - with respect to getting an intuitive feel for the algorithms.
