### Tell us what’s happening:

I’m quite sure this is the correct method, I consulted some documentation and confirmed this, i also have the correct output in the terminal, still i cannot manage to achieve a good solution to this simple exercise

### Your code so far

```
class R2Vector:
def __init__(self, *, x, y):
self.x = x
self.y = y
def norm(self):
return sum(val**2 for val in vars(self).values())**0.5
def __str__(self):
return str(tuple(getattr(self, i) for i in vars(self)))
def __repr__(self):
arg_list = [f'{key}={val}' for key, val in vars(self).items()]
args = ', '.join(arg_list)
return f'{self.__class__.__name__}({args})'
class R3Vector(R2Vector):
def __init__(self, *, x, y, z):
super().__init__(x=x, y=y)
self.z = z
# User Editable Region
v1 = R2Vector(x=2, y=3)
v2 = R3Vector(x=2, y=2, z=3)
print(f'v1 = {v1} \nrepr = {repr(v1)}')
print(f'v2 = {v2} \nrepr = {repr(v2)}')
# User Editable Region
```
