<｜begin▁of▁sentence｜>### Instruction:
You're coordinating a complex network of emergency routes, where every path between hospitals ('A' to 'B' and 'C' to 'D') carries specific characteristics such as length of time for transfer and the type of route marked by color. For clarity in a high-stress environment, you need to generate a clear and concise report that includes only the essential information: the connection between the facilities and the transfer time. Other details, like the route type, are not needed for this immediate task. 

Your goal is to create a file, let's call it 'emergency_routes.edgelist', that lists each hospital connection along with the associated transfer time, precisely. For instance, the path from 'A' to 'B' is logged with a transfer time of 7 minutes, and the route from 'C' to 'D' with a time of 5 minutes. Distractions such as the routes' color codes are omitted to streamline the decision-making process in dispatching the emergency services. Can we set up this report to assist in optimizing our response times?
### Response:
import networkx as nx

# Create a graph
G = nx.Graph()

# Add edges with weight and color attributes
G.add_edge('A', 'B', weight=7, color='red')
G.add_edge('C', 'D', weight=5, color='blue')

# Write the edge list to a file including the 'weight' attribute
nx.write_edgelist(G, 'edges.edgelist', data=['weight'])
