I have tried both using G=nx.Digraph and G=nx.Multidigraph. Table generation error: ! I have tried several things like emitting conversations where 0 emotions where exchanged, but this mostly just skews the results and still leads to a reciprocity of 0. By convention None is not used as a node. Create an empty graph structure (a null graph) with no nodes and That is, I have nodes A and B and edges (A,B) with length=2 and (B,A) with length=3. MultiDiGraph.add_node(node_for_adding,**attr). This is important because reciprocity is calculated as the ratio of reciprocal edges to total edges.
