Python Booleans: Use Truth Values in Your Code – Real Python

Because of this, True, False, not, and, and or are the only built-in Python Boolean operators. Comparison Operators. Some of Python’s operators check whether a relationship holds between two objects. Since the relationship either holds or doesn’t hold, these operators, called comparison operators, always return Boolean values. Comparison operators are the most common source of Boolean values.

Python Boolean Operators explained with Examples - ToolsQA

In the last chapter Python bitwise operators", we learned python bitwise operators, their types, and their usage in Python. Python bitwise operators work on the bit level. Even though you may have two operands to be considered, they would work bit by bit to produce the desired result. Additionally, Python boolean operators are similar to python bitwise operators in the sense that instead of bits here, we consider complete boolean expressions.

Boolean list initialization – Python - GeeksforGeeks

We are given a task to initialize a list of boolean values in Python. A boolean list contains elements that are either True or False. Let's explore several ways to initialize a boolean list in Python. Using List Multiplication. The most efficient way to initialize a boolean list with identical values is by using list multiplication. This approach creates a list with a predefined length and assigns the same boolean value to all elements.
