Hi, You can use edge_endpoint_property: https://graph-tool.skewed.de/static/doc/graph_tool.html#graph_tool.edge_endpoint_property
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 <[email protected]> wrote: > Hi, > > I would like to create a function which quickly exports a Graph to an edge > list in Python.
