Description
One can relabel a graph to 0,...,n1 by just calling .relabel()
, and I found myself typing IS.relabel({v:i for i,v in enumerate(IS.ground_set())})
very often these last days.
With this patch one can relabel the point automatically to 0,...,n1
.

Hello,
Compared with the possibilities from graph:
 what about a
inplace
argument?  what about accepting lists as input. The following works with graphs
sage: G = Graphs(... whatever on [0,1,2,3] ...) sage: G.relabel([2,0,1,3])
In the branch I updated (rebase over sage4.6) I added a commit which do these changes. I also added a nice test which illustrate the usefulness of these additions. What do you think ?
Vincent

PS: If you have more work based upon this branch I will instead base my commit over yours after a merge of 64.beta6 (switching between beta4/beta6 is a mess).

Hellooooo !
Well, I don't think I have anything based atop of that. Though you seem to need a 'copy' function that was added in #17047. Though I suppose that copy
will call it.
However, it would be cool if you could indent the description of the different types for inplace
so that it is a member of the item that begins with ``inplace``  If ``True`` then ...
.
Also, there is no .points()
function, what we have is ground_set
.
Short of that it's all fine, thanks !
