To compute the slice indexer for input labels, use the index.slice_indexer() method. At first, import the required libraries −import pandas as pdCreate Pandas index object −index = pd.Index(list('pqrstuvwxyz')) Display the Pandas index −print("Pandas Index...", index)Get the slice indexer. The "start" is the label to begin with. The "end" is the label to end with −print("The slice indexer with start and stop...", index.slice_indexer(start='s', end='w')) ExampleFollowing is the code −import pandas as pd # create Pandas index object index = pd.Index(list('pqrstuvwxyz')) # Display the Pandas index print("Pandas Index...", index) # Return the number of elements in the Index print("Number ...
