<｜begin▁of▁sentence｜>### Instruction:
Given a graph with the edge set `[(0, 1), (0, 2), (1, 3), (2, 3), (3, 4), (4, 5)]` and edge capacities `[5, 10, 15, 20, 25, 30]`, can you use `write_dimacs` method to write the graph to a file in DIMACS format, specifying that vertex 0 is the source and vertex 5 is the target?
### Response:
from igraph import Graph

# Define the edges for the graph and their capacities
capacities = [5, 10, 15, 20, 25, 30]
edges = [(0, 1), (0, 2), (1, 3), (2, 3), (3, 4), (4, 5)]

# Create the graph with the defined edges
g = Graph(edges=edges)

# Add the capacities as an edge attribute
g.es['capacity'] = capacities

# Write the graph to a DIMACS formatted file
file_name = 'graph.dimacs'
g.write_dimacs(f=file_name, source=0, target=5)

print(f'Graph written to {file_name} in DIMACS format.')
