Re: [igraph] Nodes at a given distance

Oh, ok!

I am using just python+igraph, that's why i was unable to find the setdiff. :)

I guess that now that i know what setdiff does, i can find or write
something that does the same in python.

thanks again,

marco

è il gioco della vita,

che non ci sfugga dalle dita
