This guys has a lot of nice material, presented in a clear and approachable way (this week I was teaching Python and I was linking him a lot).

For example:

Can anyone explain the different between pivot() and pivot_tables()?

Anyone hitting an error for:

table.query('Status == ["pending","won"]')

AttributeError: 'Categorical' object has no attribute 'flags'

Most people likely have experience with pivot tables in Excel.

Uhh, really?

Maybe that's true for their target audience. I suppose broadly speaking most people never used Excel. Also, most people never -- or very seldomly -- use computers.

If you're talking globally that's true, but do you think that's still true for modern industrialized nations? (USA/Canada/Western Europe/Japan/etc.)
