Hi, You can use edge_endpoint_property: https://graph-tool.skewed.de/static/doc/graph_tool.html#graph_tool.edge_endp... The example in that page is getting a numpy array of source vertices for all edges. It's very fast. - Ilkka On Tue, Mar 22, 2016 at 11:23 AM, Josh Levy-Kramer <josh@starcount.com> wrote:
Hi,
I would like to create a function which quickly exports a Graph to an edge list in Python. Bassically the opposite to the `Graph.add_edge_list` method. My current solution is:
edge_list = [ [int(e.source()), int(e.target())] for e in g.edges()]
As you can imagine this is very slow as the iteration is done in Python and not C++. Has anyone done this before, or knows how to do this at C++ speed?
Many thanks,
