<｜begin▁of▁sentence｜>### Instruction:
As an insurance agent, imagine you have a client who needs to adjust their insurance policy to reflect changes in their business operations. You need to update the coverage and policy details to ensure they are adequately protected. In this scenario, how would you use the Gephi Graph Streaming API in Python to modify the attributes of an existing policy (represented as an edge with ID 'e0') by generating an event using GephiGraphStreamingAPIFormat? This could involve changing the weight and label attributes of the edge to accurately reflect the updated coverage and policy information.
### Response:
from gephistreamer import graph

streamer = graph.Streamer('http://localhost:8080/workspace0?operation=updateGraph')

# Change edge attributes for edge with id 'e0'
edge_data = {'weight': 2.5, 'label': 'updated edge'}
change_edge_event = graph.GephiGraphStreamingAPIFormat.get_change_edge_event('e0', edge_data)
streamer.send(change_edge_event)
<|EOT|>
