Python Pandas - Compute slice locations for input labels

To compute slice locations for input labels, use the index.slice_locs() 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 locations. The "start" is the label to begin with. The "end" is the label to end with

print("\nThe slice locations with start and stop...\n",index.slice_locs(start='q', end='v'))

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 locations
# The "start" is the label to begin with
# The "end" is the label to end with
print("\nThe slice locations with start and stop...\n",index.slice_locs(start='q', end='v'))

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 locations with start and stop...
(1, 7)
