George Boole, (born November 2, 1815, Lincoln, Lincolnshire, England—died December 8, 1864, Ballintemple, County Cork, Ireland), English mathematician who helped establish modern symbolic logic and whose algebra of logic, now called Boolean algebra, is basic to the design of digital computer circuits.

What are the 3 logic gates?

The basic types of logic gates are the INVERTER (NOT gate), AND, OR, NAND, NOR, and XOR gates. Examples of the various 2-input gates are illustrated using simple analog switching circuits. The symbols for the various logic gates are illustrated along with their Boolean expressions and Truth Tables.

What is Boolean in coding?

In computer science, a boolean or bool is a data type with two possible values: true or false. It is named after the English mathematician and logician George Boole, whose algebraic and logical systems are used in all modern digital computers.

What is the value of true in 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 ….The or Boolean Operator.
