Python - Check if the Pandas Index only consists of integers

To check if the Pandas Index only consists of integers, use the index.is_integer() method in Pandas. At first, import the required libraries -

import pandas as pd

Creating Pandas index −

index = pd.Index([5, 10, 25, 50, 75, 100, 125, 150])

Display the Pandas index −

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

Check whether index values has only ints −

print("\nIndex values only consists of integers?\n",index.is_integer())

Example

Following is the code −

import pandas as pd

# Creating Pandas index
index = pd.Index([5, 10, 25, 50, 75, 100, 125, 150])

# 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)

# check whether index values has only ints
print("\nIndex values only consists of integers?\n",index.is_integer())

Output

This will produce the following output −

Pandas Index...
Int64Index([5, 10, 25, 50, 75, 100, 125, 150], dtype='int64')

Number of elements in the index...
8

The dtype object...
int64

Index values only consists of integers?
True
