print graph not available

[Peng Yu]

Hi,

I feel that it is inconvenient that Graph (and DiGraph) does not offer
a way to print them. I'm wondering if it is better to add a way to
print a graph.

import networkx as nx

G=nx.Graph()
G.add_node("spam")
G.add_edge(1,2)
print(G.nodes())
print(G.edges())
print(G) # This doesn't print anything.


Regards,

When you call print(G) it tries to print the graph name. In your case
a name wasn't specified so you got an empty string.

In [1]: import networkx as nx

In [2]: G=nx.Graph(name='tom')

In [3]: print(G)
tom

In [4]: G=nx.path_graph(4)

In [5]: print(G)
path_graph(4)
