<｜begin▁of▁sentence｜>### Instruction:
Given a graph with vertices representing individuals and edges representing their connections, and given a specific community assignment of individuals into groups, can you use the modularity function in igraph to evaluate how well the community assignment reflects the structure of the graph in terms of within-group versus between-group edge density?
### Response:
from igraph import Graph

# Create a graph from an edge list
edges = [(0, 1), (0, 2), (1, 2), (3, 4), (4, 5), (3, 5)]
g = Graph(edges=edges, directed=False)

# Define a clustering (community assignment)
# In this example, vertices 0-2 are in one community, and 3-5 are in another
membership = [0, 0, 0, 1, 1, 1]

# Calculate the modularity of the graph with respect to the clustering
modularity_score = g.modularity(membership)

# Print the modularity score
print(modularity_score)
