Python Booleans - W3Schools
Booleans represent one of two values: True or False. In programming you often need to know if an expression is True or False. You can evaluate any expression in Python, and get one of two answers, True or False. When you compare two values, the expression is evaluated and Python returns the Boolean answer:

Python Booleans: Use Truth Values in Your Code – Real Python
The Python Boolean type is one of Python’s built-in data types. It’s used to represent the truth value of an expression. For example, the expression 1 <= 2 is True, while the expression 0 == 1 is False. Understanding how Python Boolean values behave is important to programming well in Python. In this tutorial, you’ll learn how to:

Python Boolean - GeeksforGeeks
In Python, the bool () function is used to convert a value or expression to its corresponding Boolean value (True or False). In the example below the variable res will store the boolean value of False after the equality comparison takes place. Note: It’s not always necessary to use bool () directly.

python - Using True/False as keys - how/why does this work? - Stack ...
While they are keywords (in Python 3), True and False are still names of objects (they are, respectively bool(1) and bool(0)). So you can use them anywhere a value makes sense. Since they're hashable, that includes using them as dictionary keys. You can do:

Basic Data Types in Python 3: Booleans - Full Stack Python
Booleans enable our code to do just that. You can declare a boolean value in your code using the keywords True and False (note the uppercase). The following code would create two boolean values and assign them to variables. More commonly, a boolean value is returned as a result of some kind of comparison.

Python Booleans (With Examples) - Datamentor
In this tutorial, we will learn about Python booleans with the help of examples. A Boolean expression is an expression that evaluates to either True or False. For example, Here, result1 represents True boolean value and result2 represents False boolean value. Python has a set of comparison operators that allow us to compare two values.

Python Boolean and Conditional Programming: if.. else
First, we define a variable called door_is_locked and set it to True. Next, you’ll find an if-statement. This is a so-called conditional statement. It is followed by an expression that can evaluate to either True or False. If the expression evaluates to True, the block of code that follows is executed. If it evaluates to False, it is skipped.

Boolean Expressions in Python: Beginner to Expert - CodeSolid
Setting aside some advanced techniques for the moment, at the heart of most branching statements you’ll find a Boolean expression. A Boolean expression in Python is a combination of values or values and functions that can be interpreted by the Python compiler to return a value that is either true or false.
