<｜begin▁of▁sentence｜>### Instruction:
As a professional organizer, I often help individuals and businesses with their organization needs. One of the clients I am currently assisting has provided me with a list of rooms and their connections within their workspace. The client is looking to rename the rooms with a standardized prefix to streamline their organization process. Using custom formatting, I need to rename each room with a prefix 'Room ' and display the formatted room names to help the client visualize the newly organized workspace.
### Response:
import networkx as nx

# Create a NetworkX graph
g = nx.Graph()

# Add some edges to the graph
g.add_edges_from([(1, 2), (1, 3), (2, 4)])

# Define a custom function to format nodes
_format_mapping = lambda: {node: f'Node {node}' for node in g.nodes()}

# Use the custom formatting function to display node names
formatted_nodes = _format_mapping()
print('Formatted nodes:', formatted_nodes)
