Learn Special Methods by Building a Vector Space - Step 8

Python

Hi.

I’m on this step which asks to test ‘norm’ by passing v1 in a print call statement… well, I think I did the correct thing and even got the correct numeric output (3.605551275463989) on the console, and yet the tutorial won’t let me through… what am I doing wrong?

class Vector:
    def __init__(self, x, y):
        self.x = x
        self.y = y
        
    def norm(self):
        return (self.x**2 + self.y**2)**0.5

v1 = Vector(2, 3)
print(Vector.norm(v1))

Thank you.

Michal.

you need to call the method on v1, not use the class
v1.methodName()

HI ILM,

Thank you for that hint. I see that there are two ways to skin a cat. And this is the proper technique.

Please dont post solutions, thanks!
