<｜begin▁of▁sentence｜>### Instruction:
Given a directed graph whose edge set is [('A', 'B'), ('B', 'C'), ('C', 'A'), ('C', 'D')], can you determine if the graph consists of a single attracting component using NetworkX?
### Response:
import networkx as nx

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

# Check if the graph consists of a single attracting component
attracting = nx.is_attracting_component(G)

print('Does the graph consist of a single attracting component?', attracting)
