Python Pandas - Return the Number of elements in the underlying Index data

To return the Number of elements in the underlying Index data, use the index.size property in Pandas.

At first, import the required libraries −

import pandas as pd

Creating the index −

index = pd.Index([15, 25, 35, 45, 55])

Display the index −

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

Return the number of elements in the Index −

print("\nNumber of elements in the index...\n",index.size)

Example

Following is the code −

import pandas as pd

# Creating the index
index = pd.Index([15, 25, 35, 45, 55])

# Display the 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 a tuple of the shape of the underlying data
print("\nA tuple of the shape of underlying data...\n",index.shape)

# get the bytes in the data
print("\nReturn the bytes...\n",index.nbytes)

# get the dimensions of the data
print("\nReturn the dimensions...\n",index.ndim)

Output

This will produce the following code −

Pandas Index...
Int64Index([15, 25, 35, 45, 55], dtype='int64')

Number of elements in the index...
5

A tuple of the shape of underlying data...
(5,)

Return the bytes...
40

Return the dimensions...
