<｜begin▁of▁sentence｜>### Instruction:
Given a graph with the following edge set [('A', 'B'), ('B', 'C'), ('C', 'D'), ('D', 'E')], what is the harmonic centrality of each node?
### Response:
import networkx as nx

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

# Compute the harmonic centrality of the nodes
h_centrality = nx.harmonic_centrality(G)

# Print the harmonic centrality of each node
for node in h_centrality:
    print(f'Harmonic Centrality of {node}: {h_centrality[node]}')
