To return a sorted copy of the index, use the index.sort_values() method in Pandas. The parameter ascending is set False.At first, import the required libraries −import pandas as pdCreating Pandas index −index = pd.Index([50, 10, 70, 95, 110, 90, 30]) Display the Pandas index −print("Pandas Index...", index)Sort index values. To sort values in Descending order, set the "ascending" parameter to "False" −print("Sort the index values in descending order...", index.sort_values(ascending=False))ExampleFollowing is the code −import pandas as pd # Creating Pandas index index = pd.Index([50, 10, 70, 95, 110, 90, 30]) # Display the Pandas index print("Pandas Index...", index) ...
