Test that norm works as expected by printing the value returned by the method.

--hints--

You should call norm() on v1 and print the result.

js
({
    test: () => assert(runPython(`_Node(_code).has_call("print(v1.norm())")`))
})

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)
