Oh. So what you needed was actually map(len, G.connected_components()).
Well, this functon has been added in order to return a partition (this the

Okay. Please never define a graph with these things as vertices :-D

I find your proposition too ambiguous. For
I strongly object to removing the function to_partition as it is useful
to people (beyond FindStat), but I'm not opposed to renaming it to
something like connected_components_partition. Similar for to_graph.
Although if you want to argue about removing "one-line" functions, we

Hello,
For Graph I would remove the one line functions
- remove Graph.to_partition
- remove Graph.connected_components_number
or as a second choice
- rename Graph.to_partition -> Graph.connected_components_sizes (with
