<｜begin▁of▁sentence｜>### Instruction:
{'description': "Given a graph with the edge set [('A', 'B'), ('B', 'C'), ('C', 'D'), ('D', 'E')], how can you find the number of edges in the graph using NetworkX?", 'problem': 'We are looking to determine the number of edges present in a given graph using the NetworkX library.'}
### Response:
import networkx as nx

# Create a graph
G = nx.Graph()
G.add_edges_from([('A', 'B'), ('B', 'C'), ('C', 'D'), ('D', 'E')])

# Get the number of edges
num_edges = G.number_of_edges()
print('The number of edges in the graph:', num_edges)
