Thanks a lot for the great learning materials. I have one suggestion. Within the Tutorial Plotting and Programming in Python in the Variable and Assignment part, I would change the sentence about upper and lower case naming conventions for variables. The original statement 'upper-case letters are the conventions ... so we use lower case' is ambiguous. I guess this was just mixed up, but if not this would need further explanation in my opinion.
