<｜begin▁of▁sentence｜>### Instruction:
As a fitness instructor, I lead and instruct fitness classes, workouts, or training sessions to help individuals improve their physical health, strength, and conditioning. In this scenario, imagine I have a set of workout plans stored in a digital format, and I need to retrieve specific details about each plan. If a workout plan includes information about the type of exercises and number of repetitions, I would like to display this data. If the plan does not include this information, I need to be notified about the absence of such details.
### Response:
from igraph import Graph

# Load the graph from GML file
g = Graph.Read_GML('graph_palette.gml')

# Retrieve palette information if available in the graph attributes
palette = g['palette'] if 'palette' in g.attributes() else None

# Display the palette information or indicate if it's not present
if palette:
    print('Palette information:', palette)
else:
    print('No palette information available for this graph.')
