<｜begin▁of▁sentence｜>### Instruction:
As a networkx expert, I can certainly help you with that. Assuming we have a dataset representing a network of chemical compounds and their interactions, I might be able to create a color palette representing different molecular pathways using the RainbowPalette in networkx with 10 colors. After generating this palette, I could use the '__len__' method to determine the number of colors in the palette, providing a quantitative measure of the diversity within these molecular pathways.
### Response:
from igraph.drawing.colors import RainbowPalette

# Create a new RainbowPalette with a specified number of colors
palette = RainbowPalette(n=10)

# Use the '__len__' method to get the number of colors in the palette
number_of_colors = len(palette)

print('Number of colors in the palette:', number_of_colors)
