Statements where the value could be of type boolean string list dict set etc. A truth table for p q is shown below. So when the above code is executed it produces the following result.

That was not fun. In propositional logic double negation is the theorem that states that If a statement is true then it is not the case that the statement is not true This is expressed by saying that a proposition A is logically equivalent to not not-A or by the formula A A where the sign expresses logical equivalence and the sign expresses negation. The symbol for this is Λ.
