To answer your questions:

  • All the single aggs are good. Should also implement for .count() and .agg()/aggregate() I believe?
  • Should display the same as Pandas so will need to return a MultiIndex for the index.
  • For options you can start with only by and I think dropna should be implementable! For dropna you can add a filter that ensures a non-null/empty value for any column you’re grouping on.
