Tables of truth are tools used in evaluating logical expressions and proving arguments. The name comes from the factual nature of the mathematical table in which all possible outcomes are represented. The Tractus Logico-Philosophicus, written by Ludwig Wittgenstein in 1918 and published in 1921, is largely credited for creating and popularizing the truth table. Truth Table Generator is a program which provides a truth table for the propositional logic expression entered by the user and also confirms whether the given expression is a tautology or not. Mathematics and science that rely on Boolean logic also use truth tables to show the truth or falsity of expressions or operations. This paper contains the proposed idea for evaluating and generating truth tables for propositions using python.
