Can anyone explain this to me?
class Car:
color = 'gray'

def describeCar(self):
return 'A cool ' + Car.color + ' car'

def describeSelf(self):
return 'A cool ' + self.color + ' car'

lola = Car()
lola.color = 'plaid'
why lola.describeCar() prints 'A cool gray car' rather than 'A cool plaid car'?

is this python?

yes

because you changed the `color` attribute of `lola` to `'plaid'` with the line 
```
lola.color = 'plaid'
```
When you initialized `lola = Car()` you set the attribute `lola.color` to the default value, which is `'grey'`, but you then changed that attribute `'plaid'`  as I stated above.

This is not how you are actually supposed to change attribute values, by the way, but I'm sure you will learn a better way soon.

I didn't write this code, it was an exercise on a website and I was supposed to answer what the code will print. I thought it was "A cool plaid car" but the answers turned out to be "A cool gray car"

In the method "describedCar" is used "Car.color" which is a class attribute, "Car.color" is not same as "self.color" and is not part of the "lola" object and because of that can't be changed through the "lola.color" object attribute.
