WebAug 22, 2015 · from sympy import * x=Symbol ('x',commutative=False) y=Symbol ('y',commutative=False) print sympify (3*x*y - y*x - 2*x*y) it will print x y -y x, however if we apply sympify to the string, that is, print sympify ('3*x*y - y*x - 2*x*y') The result is 0. Is there a way of simplifying the above string to preserve non-commutativity of x and y? WebThis is the SymPy version of False, for use in the logic module. Theprimary advantage of using false instead of False is that shorthand booleanoperations like ~ and >> will work as expected on this class, whereas withFalse they act bitwise on 0. Functions in the logic module will return thisclass when they evaluate to false. puppy sleepy kitten gif
