Subject: Re: [graph-tool] Remove vertices without edges

Hi Ales,

personally I would use a filter, exploiting the methods in_degree() and out_degree().

I.e. something like

gv = GraphView(g,vfilt=lambda x: x.in_degree()+x.out_degree()>0)

If your graph is undirected, you can use only out_degree(). I strongly advise you to read the documentation, there i splenty of information there.

Best,

Giuseppe

Hi Guys!

What is the best way to remove vertices that do not have any edges?

Best,

Alex
