Feature suggestion:

I was using hackish solutions to select rows where a particular column is empty/non-empty, because I didn't know about isnull and notnull. I think these should be exposed as methods, particularly of Series (i.e. columns), so they're readily discoverable via tab completion.

Example use:

selection = df[df['col'].notnull()]
