pandas.notnull documentation showing code examples from pandas.notna

[jenkc]

The code examples are from the previous page in the documentation. Need examples for using notnull please.
Thanks!

Thanks for pointing this out @jenkc! This happens because notnull is purely just an alias for notna (the same problem exists for isnull, and the associated Series/DataFrame methods). To avoid duplicating examples, I'd guess some of the shared doc machinery could be used to generalize over isna/isnull and notna/notnull

Thanks for the clarification! Was trying to use these for the first time and did not know that notnull and isnull are aliases.

or maybe add a basic docstring to the alias to let users know it's an alias and link to the other.
