WebThis is what is meant by “assumptions” in SymPy. If the symbol y is created with positive=True then SymPy will assume that it represents a positive real number rather than an arbitrary complex or possibly infinite number. That assumption can make it possible to simplify expressions or might allow other manipulations to work. It is usually a good idea … WebNor Function. This function performs Logical NOR operation.
