<｜begin▁of▁sentence｜>### Instruction:
As a Reiki practitioner, I understand the importance of clarity and guidance in providing assistance. Imagine a scenario where a new Reiki client seeks guidance on understanding the energy flow within their body. To help them comprehend this, you might explain the concept of energy pathways, using the analogy of a river system with various tributaries merging and diverging. In this context, the client wishes to understand the multiplicity of energy flows at specific junctions within their body. They specifically want to know how these energies combine and diverge. In network terms, this is similar to understanding the "multiplicities" of edges in a graph using the `count_multiple` function in the igraph API. The client is seeking clarity on how these energy junctions interact and merge, and would like you to assist in visualizing and explaining this intricate network of energy pathways.
### Response:
from igraph import Graph

# Given a Graph g
edges = [(0, 1), (1, 2), (0, 1)]
g = Graph(edges=edges)

# Use the count_multiple function
g.add_vertex(3)  # ensuring the vertex count is correct even if it's not in edges
mult = g.count_multiple()
print(mult)
