Python Pandas - Compute the slice indexer for input labels
To compute the slice indexer for input labels, use the index.slice_indexer() method. At first, import the required libraries −
import pandas as pd
Create Pandas index object −
index = pd.Index(list('pqrstuvwxyz'))
Display the Pandas index −
print("Pandas Index...\n",index)Get the slice indexer. The "start" is the label to begin with. The "end" is the label to end with −
print("\nThe slice indexer with start and stop...\n",index.slice_indexer(start='s', end='w'))
Example
Following is the code −
import pandas as pd
# create Pandas index object
index = pd.Index(list('pqrstuvwxyz'))
# Display the Pandas index
print("Pandas Index...\n",index)
# Return the number of elements in the Index
print("\nNumber of elements in the index...\n",index.size)
# Get the slice indexer
# The "start" is the label to begin with
# The "end" is the label to end with
print("\nThe slice indexer with start and stop...\n",index.slice_indexer(start='s', end='w'))Output
This will produce the following output −
Pandas Index... Index(['p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z'], dtype='object') Number of elements in the index... 11 The slice indexer with start and stop... slice(3, 8, None)
