# Python Setter Method - what am I doing wrong?

I'm getting the error message "Didn't correctly set @price property".

I think what I have here makes sense. We want to set the base price (`_price`) attribute, which we do by dividing by 1+tax_rate. Right? What am I missing?

product.py
```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)

# this part is my code:
@price.setter
def price(self, price):
self._price = price / (1 + self.tax_rate)
```

Hi Greg,

I took it very literally to just set the price and not do any calculation on it first.

But that cannot be right.

```some_product.price = 1
print(some_product.price) #prints 1.12!!
```

The `price` property is the net price after tax. The `_price` attribute is the base price. You can't just set the base price equal to the price after tax.

Well, we don't really know the details here of how this gets used but this is how I'm reasoning it out.

You initialize the product with the base price. Whenever you get the price for the product it should be the tax adjusted price.

The base price of the product might change at some point in the future and the setter is how you would reset that base price.

I think you're probably looking at it as, the price passed in is including the tax and you need to work out the base price.

But I suspect we're just literally passing in the base price when we use the setter.
