I've also just started the course this month. So far I'm enjoying it. Coming over from York, UoL's programme is light years ahead of theirs. The topics are actually commercially relevant and there are actual video lectures - Thank God! In regard to Python, yes it would be hard if you're coming in with no knowledge at all. The activities are a huge jump from the videos which is annoying me a little. They did make people with a non CS background take a course in Python Machine Learning through Coursea before starting though, so I think it was fairly clear they wanted us to have at least a basic knowledge of Python before starting. I don't come from a CS background but taught myself Python online before starting. No disrespect to the poster above but, it's a Masters. If you're expecting them to teach you from absolute zero, it's not exactly going to be masters level, is it?
In summary for others, is it perfect? No. It still has organizational issues but they're trying to fix it and the head of the programme really cares about making it good. As a whole, I can recommend it, just don't expect gold. The syllabus is good and, importantly, relevant. It's better than many other programmes, especially given the price, but if you want to pay more for a high end one, you can probably find better.
