Note And Edge Attributes

Adding node and edge attributees:

G=nx.Graph()
G.add_edge('A','B',weight=6,relation='family')
G.add_node('A',role = 'trader')

Accessing node attributes:

G.nodes()  //list of all nodes
G.nodes(data=True)  //list of all nodes with attributes
G.node['A']['role']  //role of A

out:['A','B']
    [('A','role':'trader'),('B','role':'trader')
    'trader'

Accessing Edge attributes:

G.edges(data=True)  //list of all edges with attributes
G.edges(data='relation')  //list of all edges with attribute 'relation'
G.edge['A']['B']['weight']  //weight of edge (A,B)

out:[('A','B',{'relation':'family','weight':'6'})]
    [('A','B','family')]
