I think you did not fully understand the purpose of properties.

If you create a property x, you'll accessing it using obj.x instead of obj.x(). After creating the property it's not easily possible to call the underlying function directly.

If you want to pass arguments, name your method get_x and do not make it a property:

def get_x(self, neg=False):
    return 5 if not neg else -5

If you want to create a setter, do it like this:

class A:
    @property
    def x(self): return 5

    @x.setter
    def x(self, value): self._x = value
