I'm analizing Marvels Social Network I have this code:
import numpy
import pandas
import networkx as nx
import unicodecsv as csv
data = pandas.read_csv('hero-network.csv', low_memory=False)
def graph_from_csv(path):
graph = nx.Graph(name="Heroic Social Network")
with open(path, 'rU') as data:
reader = csv.reader(data)
for row in reader:
graph.add_edge(*row)
return graph.size()
graph_from_csv(data)
I'm new to python. And I'm not quite sure why my code has this kind of output insted of the graphs size:

What am I doing wrong, how can I make the code to output the size of the graph. And also I have an type error but the same csv file is used in the manual where I found this code and they aren't getting the type error, but just the output with the numeric size of the graph.
