Dataframes ready to be imported?

[amelio-vazquez-reina]

Does Pandas come with any "sample" dataframes ready to be imported? Otherwise, does the library provide any utilities to quickly create them randomly? (aside from the usual np. random utils). I'm thinking of examples with timestamps, categorical and numerical data.

Alternatively, are there any recommended packages that can help users load "sample" dataframes/series/panels?
