Python - Check if the Pandas Index only consists of booleans

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

import pandas as pd

Creating Pandas index

index = pd.Index([True, True, False, False, True, True, True])

Display the Pandas index −

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

Check whether index values have only booleans −

print("\nIndex values only consists of booleans?\n",index.is_boolean())

Example

Following is the code −

import pandas as pd

# Creating Pandas index
index = pd.Index([True, True, False, False, True, True, True])

# 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 booleans
print("\nIndex values only consists of booleans?\n",index.is_boolean())

Output

This will produce the following output −

Pandas Index...
Index([True, True, False, False, True, True, True], dtype='object')

Number of elements in the index...
7

The dtype object...
object

Index values only consists of booleans?
True
