I do not know why it says "Couldn't import 'Product.'"

I looked up for the solution(s) and my codes are similar to them. However, I get this message "Couldn't import 'Product.'" I have been stuck here for an hour and I do not know how to fix this. I appreciate your help. Thanks.

product.py 
class Product:
    _price = 0.0
    tax_rate = 0.12

    def __init__(self, base_price):
        self._price = base_price

    @price.setter
    def price(self, next_price):
        self._price = next_price

Oh, and the question asked me to add a new setter (@price.setter) method to the Product class that updates the _price attribute.

Hi there,

You've removed some code from the challenge which is causing the issue. If you leave that in and just add your code, it'll pass the challenge:

class Product:
    _price = 0.0
    tax_rate = 0.12

    def __init__(self, base_price):
        self._price = base_price

    @property
    def price(self):
        return self._price + (self._price * self.tax_rate)

    @price.setter
    def price(self, next_price):
        self._price = next_price

Steve.
