# Learn Special Methods by Building a Vector Space - Step 19

### Tell us what’s happening:

Dear Team,
why my prints line 19 and 20 do not pass the code? and indeed the these
print(v1.dict)
print(v2.dict)
pass the code?
I read the python vars() is used to retunr the value of the __dict_attribute
As usual probably I miss something here…sorry

``````
class R2Vector:
def __init__(self, *, x, y):
self.x = x
self.y = y

def norm(self):
return (self.x**2 + self.y**2)**0.5

def __str__(self):
return f'{self.x, self.y}'

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(vars(v1))
print(vars(v2))

# User Editable Region

and the output is the same for both couple of printing:
{‘x’: 2, ‘y’ : 3}
{‘x’ : 2, ‘y’ : 2, ‘z’ : 3}

Dot `.` onto the vectors and use `__dict__`

``````someVector.__dict__
``````

yes, I used this one and passed the code. But also using the vars() I am getting the same output but the code doesn’t pass.

This step is explicitly asking you to use `__dict__` and tests are checking for that.

But yes, the result is the same.
