18. Operator Overloading

Redefine how operators behave for your custom classes.

Example

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

    def __add__(self, other):
        return Vector(self.x + other.x, self.y + other.y)

    def __repr__(self):
        return f"Vector({self.x}, {self.y})"

print(Vector(1,2) + Vector(3,4))

Wrap-Up

• Operator overloading makes custom objects behave like built-ins.
