8. Gogo has created a list of connections in his classroom. Each connection is represented as a tuple of two individuals who are friends. Gogo needs to create an undirected graph and find the number of nodes and edges in the graph.
Connections = [(‘Jagirat’,’Jatin’), (‘Jagirat’, ‘Ashutosh’), (‘Jatin’, ‘Gitansh’), (‘Ashutosh’,’Gitansh’), (‘Gitansh’,’Nishit’)]
import networkx as nx
def class_network(Connections):
G = nx.graph()
G.add_edges_from(Connections)
num_nodes = G.number_of_nodes()
num_edges = G.number_of_edges()
return num_nodes, num_edges
print(class_network(Connections))
- (4,5)
- (5,4)
- (5,6)
- (6,5)
- (5,5)
- (4,4)
- (6,6)
- (4,6)
Answer :- e
