<｜begin▁of▁sentence｜>### Instruction:
As a blockchain developer, you might encounter a scenario where you need to determine whether a network of transactions has multiple occurrences of the same transaction between parties. You can utilize the capabilities of the igraph API to check if the graph representing these transactions has multiple edges between any pair of nodes. This would allow you to ensure the integrity of the transaction data and the security of the network.
### Response:
import igraph as ig

# Create a graph with possible multiple edges
g = ig.Graph([(0, 1), (1, 2), (2, 3), (3, 0), (0, 1)])

# Check for multiple edges
has_mult_edges = g.has_multiple()

print('Graph has multiple edges:', has_mult_edges)
