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
