Tribool
In logic, a three-valued logic (also trinary logic, trivalent, ternary, or trilean, sometimes abbreviated 3VL) is any of several many-valued logic systems in which there are three truth values indicating true, false and some third value. This is contrasted with the more commonly known bivalent logics (such as classical … See more Around 1910, Charles Sanders Peirce defined a many-valued logic system. He never published it. In fact, he did not even number the three pages of notes where he defined his three-valued operators. Peirce soundly rejected the … See more SQL The database structural query language SQL implements ternary logic as a means of handling comparisons with NULL field content.

(This may be made clear by considering all possible truth tables for an arbitrary unary operator.

WebTribool is an Apache2 licensed Python module that implements three-valued logic. Suppose for a moment that you're attempting to store a value across a network connection. You begin with a simple protocol in which the server stores the received value and then sends an acknowledgement to the client. In this design, the client experiences a delay ... WebMar 12, 2015 · Tribool provides tri-state logical operators that act like their boolean counterparts. The logic tables are documented below. Parsing. The tribool package is especially useful for parsing flags that may need a default value.
