Delete a group after pandas groupby


Is it possible to delete a group (by group name) from a groupby object in pandas? That is, after performing a groupby, delete a resulting group based on its name.

Filtering a DataFrame groupwise has been discussed. And a future release of pandas may include a more convenient way to do it.

But currently, here is what I believe to be the most succinct way to filter the GroupBy object grouped by name and return a DataFrame of the remaining groups.


And here is a more general method derived from the links above:

df[grouped[0].transform(lambda x: != group_name).astype('bool')]
