Equivalent of R igraph graph_from_data_frame() function in Python igraph?

Question

Is there an equivalent of this igraph R function in Python igraph?

graph_from_data_frame(d, directed = TRUE, vertices = NULL)

This function creates an igraph graph from one or two data frames containing the (symbolic) edge list and edge/vertex attributes.

Answer 1

Python does not have data frames so there is no direct equivalent. The closest equivalent could be Graph.DictList , which creates a graph from a list of dictionaries, or Graph.TupleList , which is the same for a list of tuples.

Answer 2

Right now you can use this:

from igraph import Graph
g = Graph.DataFrame(edges, directed=False, vertices=vertices, use_vids=False)

where "edges" is the dataframe with the edges, vertices are the names that will be used in each vertex, and use_vids if you want to assign indexes to name the edges instead of using the "vertices" data
