TPDeramus commented on issue #38747:

   Managed to solve issue 1., though probably not as elegantly as I could have, by using the following to generate a list of lists with the summary variable(s):
   
   ```
   grenerator = [([x for x in table.schema.names if "c" in x][i], "mean") for i in range(len([x for x in table.schema.names if "c" in x]))]
   table.group_by("IDs").aggregate(grenerator)
   ```
   
   The second part however, still eludes me.
   
   Would I be better off filtering by ID and then running the `mode` call individually and appending?
