Tell us what’s happening:

hi ,guys! I can’t fix this. when I write like this, it returns the ‘norm’ is not defined. but if I put 4 blank space in the front, it returns ‘indentation error’. please help me! thanks!

Your code so far

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(norm(v1))

norm is an object method, so you’ll need to reference the object first, like this:

object.method()

You’ve instantiated an object called v1
