Prerequisites for the Courses

I've been taking a few courses on this platform. What are the prerequisites for these courses? Are you assuming zero knowledge? One thing I recommend is to clarify the exact prerequisites for each course. I started taking the Machine Learning in Python course, and I realize that I may lack some of the fundamentals going into this course, for example, seaborn. Without a pre-req in data visualization with Python, it's more challenging to follow. It's a great course and so are the other courses, but just for the benefit of students, it'd be useful to show which pre-reqs are needed going into each course. Thanks.
