<｜begin▁of▁sentence｜>### Instruction:
{'description': 'Suppose we have a graph with 5 nodes and the following edges: [(0, 1), (1, 2), (3, 4)]. How many isolates are there in this graph, where an isolate is defined as a node with no connections to other nodes?', 'problem': 'The problem is to count the number of nodes in the graph that have no edges connected to them, using NetworkX.'}
### Response:
import networkx as nx

# Create a graph
G = nx.Graph()
G.add_nodes_from(range(5))
G.add_edges_from([(0, 1), (1, 2), (3, 4)])

# Count the number of isolates
num_isolates = nx.number_of_isolates(G)

print('Number of isolates in the graph:', num_isolates)
