### Tell us what’s happening:

Either I do not understand the request or do not know how how to implement this to satisfy the code check.

help!

v1 = (2, 3)

v2 = (0.5, 1.25)

v3 = v1 * v2

### 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})'
def __add__(self, other):
if type(self) != type(other):
return NotImplemented
kwargs = {i: getattr(self, i) + getattr(other, i) for i in vars(self)}
return self.__class__(**kwargs)
def __sub__(self, other):
if type(self) != type(other):
return NotImplemented
kwargs = {i: getattr(self, i) - getattr(other, i) for i in vars(self)}
return self.__class__(**kwargs)
# User Editable Region
def __mul__(self, other):
if type(other) in (int, float):
kwargs = {i: getattr(self, i) * other for i in vars(self)}
return self.__class__(**kwargs)
elif type(self) == type(other):
print( {i: getattr(self, i) * getattr(other, i) for i in vars(self)} )
kwargs = 0
for l in {getattr(self, i) * getattr(other, i) for i in vars(self)} :
kwargs+= l
print(kwargs)
return self.__class__(**kwargs)
# User Editable Region
class R3Vector(R2Vector):
def __init__(self, *, x, y, z):
super().__init__(x=x, y=y)
self.z = z
```

using the following:

v1 = (2, 3)

v2 = (0.5, 1.25)

v3 = v1 * v2

The code below returns a valid tuple - {‘x’: 1.0, ‘y’: 3.75}. Is a valid overload of multiply with a valid return.

Works when I create and multiple a new vector object in a series (v1 * v2 * v3)

```
def __mul__(self, other):
if type(other) in (int, float):
kwargs = {i: getattr(self, i) * other for i in vars(self)}
return self.__class__(**kwargs)
elif type(self) == type(other):
kwargs = ( {i: getattr(self, i) * getattr(other, i) for i in vars(self)} )
return self.__class__(**kwargs)
```

Conversly the following is my implemenation of scalar product.

(2 *.05) + (3* 1.25) = 1.0 + 3.75 = 4.75

Returns the correct product 4.75.

The code returns the error - typeError: **main**.R2Vector() argument after ** must be a mapping, not float

```
def __mul__(self, other):
if type(other) in (int, float):
kwargs = {i: getattr(self, i) * other for i in vars(self)}
return self.__class__(**kwargs)
elif type(self) == type(other):
for l in {getattr(self, i) * getattr(other, i) for i in vars(self)} ):
kwargs+= l
return self.__class__(**kwargs)
type or paste code here
```

Not sure how to resolve the request and pass the ‘Check your Code’.
