<｜begin▁of▁sentence｜>### Instruction:
As a retail buyer, I'm responsible for selecting and purchasing merchandise for my retail stores or online retail platform. In this scenario, I need to use the complementer function in igraph to obtain the complement of a simple undirected graph without loops. It can be compared to selecting and complementing a new set of products to ensure a diverse and well-rounded inventory that appeals to a wide range of customers.
### Response:
from igraph import Graph

# Define a simple undirected graph
edges = [(0, 1), (1, 2), (2, 3)]
g = Graph(edges=edges)

# Get the complement of the graph
complement_graph = g.complementer(loops=False)

# Print edges of the complement graph
print(complement_graph.get_edgelist())
