To compute indexer and mask for new index given the current index, use the index.get_indexer() method in Pandas.At first, import the required libraries −import pandas as pdCreating Pandas index −index = pd.Index([10, 20, 30, 40, 50, 60, 70]) Display the Pandas index −print("Pandas Index...", index)Compute indexer and mask. Marked by -1, as it is not in index −print("Get the indexes...", index.get_indexer([30, 40, 90, 100, 50])) ExampleFollowing is the code −import pandas as pd # Creating Pandas index index = pd.Index([10, 20, 30, 40, 50, 60, 70]) # Display the Pandas index print("Pandas Index...", index) # Return the ...

To return the label from the index if all of the labels in the index are later than the passed label, use the index.asof() method in Pandas.At first, import the required libraries −import pandas as pdCreating Pandas index −index = pd.Index([10, 20, 30, 40, 50, 60, 70]) Display the Pandas index −print("Pandas Index...", index)Return the label from the index. Returns NaN when if all of the labels in the index are later than the passed label −print("Get the label from the index...", index.asof(6)) ExampleFollowing is the code −import pandas as pd # Creating Pandas index index = pd.Index([10, 20, ...
