Hello, I am new on this mailing list, a casual sage user for several years who would like to contribute to sage. My first message here is about a minor issue.
I noticed that the neighbor_iterator method does not give a correct error message when given a vertex that does not belong to the graph. sage: g = Graph() sage: list(g.neighbor_iterator(123)) LookupError: vertex (-1) is not a vertex of the graph The issue is that '-1' is not the name of the vertex that I tried to delete. Same behavior with g.vertices(123), which uses neighbor_iterator. I did not find any mention of this behavior online. Sage version: 8.5 2018-12-22. I think I know how to fix it. Should I open a trac ticket? Best regards, Jean-Florent. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
