What does this mean?

It will filter out the Groups that have less than 3 companies in that particular group.

Hi Sebastian,



The filter() function will filter out (i.e., remove) the groups that do not satisfy the condition represented by the lamda function.

So, the code is essentially filtering out (removing) the groups that have less than three elements, and only the groups that meet the condition will be included in the output.



Thanks.
