To avoid this ambiguity, Pandas supports the syntax data.loc['a'] as an alternative way to filter using the index. Pandas also supports the syntax data.iloc[n], which always takes an integer n and returns the nth value, counting from 0. This allows a ...
Row labels are used to apply a filter to one or more rows that have to be shown in the pivot table.

There will also ...

Indexes on sparse columns are also optimized: only those rows with values are indexed. In addition, the contents of all sparse columns in a particular row of a table can be collectively aggregated into a single XML column (a column set), whose contents are of the form [<column-name>column contents </column-name>]*....
