Boolean False
sympy.logic.boolalg.BooleanFalse
Boolean False in SymPy is a singleton that can be accessed with S.false, or by directly importing false or by importing simplify from the sympy package.
Python3
# import packagesfrom sympy import falsefrom sympy import S, sympify# prints Falseprint(false)# prints Falseprint(S.false)# prints Falseprint(sympify(false)) |
Output:
False False False
negation of true is false, and negation of false is true.
Python3
# import packagesfrom sympy import false, trueprint(~true,~false) |
Output:
False True
What are the Logical Expressions in Sympy?
SymPy is a symbolic mathematics Python package. Its goal is to develop into a completely featured computer algebra system while keeping the code as basic as possible to make it understandable and extendable. The package is entirely written in python language. Logical expressions in sympy are expressed by using boolean functions. sympy.basic.booleanarg module of sympy contains boolean functions.
The common Python operators & (And), | (Or), and ~ (Not) can be used to create Boolean expressions. >> and can also be used to create implications. other boolean operations or gates are NAND, NOR, XOR, etc.
