How to Reduce Instance Memory with __slots__ in Python

Demonstrates that classes with __slots__ use less memory per instance than regular classes because they skip the instance __dict__.

__slots__ memory performance
Python 
class SlottedPoint:
    __slots__ = ('x', 'y', 'z')

    def __init__(self, x, y, z):
        self.x = x
        self.y = y
        self.z = z


class RegularPoint:
    def __init__(self, x, y, z):
        self.x = x
        self.y = y
        self.z = z


if __name__ == "__main__":
    regular = RegularPoint(1, 2, 3)…
