Why does the code not work for magicattr_start.py when specifying an else clause for __setattr__

[jeffl24]

Issue Overview

For the file magicattr_start.py, you used the code:
`

def __setattr__(self, name, value):
    if name == 'price':
        if type(value) is not float:
            raise ValueError(
                "The price attribute must be a float data type")
    return super().__setattr__(name, value)

`

I tried to add an else clause right before the final return statement, to make my code more explicit:

`

def __setattr__(self, name, value):
    if name == 'price':
        if type(value) is not float:
            raise ValueError(
                "The price attribute must be a float data type")
    else: 
        return super().__setattr__(name, value) 

`
However this throws an error: "AttributeError: 'Book' object has no attribute 'price'".

I tried searching on stackoverflow and using ChatGPT to find out what is the reason behind this, but to no avail.

Could you please help? Thank you!
