As I am starting to learn Python I do not do the tasks. I have not learned a lot, but found I really liked the explanations of the list operations like:
set(Object x, int index)
As they made it much more clear what was actually happening.

I did have problems when you were trying to explain the concept, but referencing two languages and not always being clear on the differences in use between the two or only showing examples in java.

I have written basic programs in several languages thru the years and understand most of the basics shown before lists. I have not done enough programming in Python to be comfortable trying to learn any OOP concepts yet.
