I am just starting to dabble in python. And just to let you know I was
watching a pycon (or somecon) and the speaker asked the audience
"How many of you are programmers?" 
Result: Lots of hands raised.

"How many people think programming skills are inherent?"
i.e. that some people are just born with the gift to be good programmers
Result: very few hands raised maybe a couple (possibly non-progammers??)

Anyway there's reason to keep at it and slog your way through to proficiency.
Because you will become proficient.  It's like reading a book by Neal Stephenson,
you read along and say wtf, but you keep reading and things start making some
sense....or learning to play a musical instrument or the like.

Anyway I've taken a stab at these but I won't be the spoiler. Although I admit
that a couple of lessons are unclear to me. For example "Do I get extra points
if I don't use nested loops where I don't need them?". Or do I get marked down?

I've completed the rows/columns of 123456 and the chessboard but the others
are not clear. I did the squareroot problem but that's unclear.
