How to read data from file for NetworkX graph

Question

I am having issues trying to read in the following data from a file into NetworkX to build a graph.

Example Data:

The pipe '|' separates the source node (user) from the destination nodes (users). As an example entry:

s1|d1,d2,d3

means that there is an edge between user s1 and user d1, and there is also an edge between user s1 and user d2, etc.

You can use str.split() to split the lines and parse accordingly. Example:

G = nx.Graph() with open('g.txt') as f: for line in f: u, destinations = line.split('|') for v in destinations.split(','): G.add_edge(u,v)
