<｜begin▁of▁sentence｜>### Instruction:
As a physicist, I analyze complex systems to understand underlying principles. If provided with a specific directed graph and a list of edges, I can evaluate whether the relationship between two vertices is mutual. For example, consider a scenario where I am studying the flow of particles through a network of channels, and I need to determine if the flow between two channels is reciprocal. Given the graph and vertex data, I can employ networkx, a Python library for studying complex networks, to analyze the directed graph and check for mutual connections between vertices.
### Response:
from igraph import Graph

# Create a graph with edges
edges = [(0, 1), (1, 0), (1, 2), (2, 3)]
g = Graph(edges=edges, directed=True)

# Get an Edge object
one_edge = g.es.select(0, 1)  # Select the edge between vertex 0 and 1

# Check if the edge is mutual
is_mutual = one_edge.is_mutual()
print('Is the edge mutual?', is_mutual)
