Repeat Elements of an Index in Python Pandas

To repeat elements of an Index, use the index.repeat() method in Pandas. Set the number of repetitions as an argument. At first, import the required libraries −

import pandas as pd

Creating Pandas index −

index = pd.Index(['Car','Bike','Airplane', 'Ship','Truck','Suburban'], name ='Transport')

Display the Pandas index −

print("Pandas Index...\n",index)

Repeat elements of the index −

print("\nResult after repeating each index element twice...\n",index.repeat(2))

Example

Following is the code −

import pandas as pd

# Creating Pandas index
index = pd.Index(['Car','Bike','Airplane', 'Ship','Truck','Suburban'], name ='Transport')

# 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)

# Return the dtype of the data
print("\nThe dtype object...\n",index.dtype)

# repeat elements of the index
print("\nResult after repeating each index element twice...\n",index.repeat(2))

Output

This will produce the following output −

Pandas Index...
Index(['Car', 'Bike', 'Airplane', 'Ship', 'Truck', 'Suburban'], dtype='object', name='Transport')

Number of elements in the index...
6

The dtype object...
object

Result after repeating each index element twice...
Index(['Car', 'Car', 'Bike', 'Bike', 'Airplane', 'Airplane', 'Ship', 'Ship',
'Truck', 'Truck', 'Suburban', 'Suburban'],
dtype='object', name='Transport')
