Boolean Logic
00:00 In this lesson, you’ll get a bit of a background about what Boolean logic is.
00:06 Boolean logic is named after George Boole, who developed a whole system of mathematics based on two values called true and false and the operations on them, three of them: AND, OR, or NOT. Since computers work in binary—two values, although we call them 1 and 0—Boolean algebra became the natural way to design and build computers.

Boolean expressions are the types of expressions we use in if and while statements. Using Boolean operators can allow you more precise and sometimes more complicated conditions to describe which branch of an if statement to execute or when to repeat an iteration in a while loop. In the next lesson, we’ll actually take a look at some terms important to using Boolean logic in Python.
