I agree, with reservations. Python is great for introducing people to programming; however, it is not necessarily great for teaching computer science concepts.

My 200 level data structures and algorithms class was taught in Python, and it just felt awkward. For example, we constructed an "array" by basically creating an abstraction on top of a list, which did nothing but remove features and introduce overhead. It kind of felt like teaching someone how to make a bike by taking all four wheels off of a car and only putting two back.
