<｜begin▁of▁sentence｜>### Instruction:
In examining the structural dynamics of a local political landscape, we're looking at a simplified model where the political entities are represented by points labeled 1, 2, 3, and 4. These points are connected by lines signifying alliances or partnerships, specifically between entities 1 and 2, and between entities 3 and 4. Our objective in this analysis is to determine the count of political entities that currently stand alone in this model, without any alliances. This will provide us with insight into the interconnectedness of our political entities and help us understand the level of political isolation within this system.
### Response:
import networkx as nx

# Create a graph with isolated nodes
G = nx.Graph()
G.add_nodes_from([1, 2, 3, 4])
G.add_edges_from([(1, 2), (3, 4)])

# Calculate the number of isolated nodes in the graph
isolates_count = nx.number_of_isolates(G)

print('Number of isolated nodes:', isolates_count)
