Python has many primitive data types, and “bool” is one of them. In this tutorial, we will see what a boolean value is and how to declare a boolean value.
The boolean data type can have only two values: True and False.
The primary use of boolean values in Python is to check if the statement is Truthy or Falsy values.
How to declare a boolean value in Python
To declare a boolean value in Python, assign a True or False value to a variable. For example, variable a = True or a = False. The variable a becomes a boolean now.
You can represent boolean values as 0 and 1, which is a much better way to store them as integers in real-world applications.
data = True info = False ai = 1 human = 0 print(data) print(type(data)) print(info) print(type(info)) print(ai) print(type(ai)) print(human) print(type(human))
True <class 'bool'> False <class 'bool'> 1 <class 'int'> 0 <class 'int'>
You can see that type() function returns the data type of a variable.
For values like True or False, it returns class “bool”; for values like 0 and 1, it returns class “int”.
Python bool() function
The bool() is a built-in Python function that converts any value to a boolean (True or False) value.
The following values in Python are considered False.
You can explicitly use the bool() function to convert a value to a boolean.
That’s it for this tutorial.
