Boolean Not
sympy.logic.boolalg.Not(arg)
Not represents negation. If the statement is False, this method returns True. If the assertion is true, it returns False.
Python3
# import packagesfrom sympy.abc import xfrom sympy.logic.boolalg import Not# nor formulaprint(Not(x))# ~True == Trueprint(Not(True))# ~False == Falseprint(Not(False)) |
Output:
~x 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.
