Treehouse Guest TeacherYou are really close but in your last answer to this question, you are trying to return hours(...)
. hours
, in this scope is not a defined variable. hours
is the name of your method on your Store
class. Once this method has been called/invoked, you don't need to return hours()
. You're already in the method, just build your formatted string and return it.
class Store:
open = 9
close = 9
Starting out very simply, we create a Store
class with two properties for open
and close
. This part you have correct.
class Store:
open = 9
close = 9
def hours(self):
return "We're open from {} to {}".format(self.open, self.close)
The hours
method simply needs to return a formatted string making sure to reference open/close properties from self
.
I believe that you are misunderstanding how the hours
method will be called, so maybe an example of the Store
class in use would make more sense.
store = Store()
Here you create an instance
of your Store
object named store
. From this store
instance, you want to print out the store hours somewhere in your code. To do this, you simply call the hours
method on your store
instance.
print(store.hours())
>>> "We're open from 9 to 9."

There is a problem with the:
return self.hours = ...
Also you're not using the properties of the current object with: format(open, close). It should be:
format(self.open, self.close)
Kenneth Love
Treehouse Guest TeacherYou can't really return an assignment, so just return the .format()
-ed string.
And, like David Bouchare pointed out, you'll need to use self
on those instance attributes.

6,002 PointsThis is befuddling.
class Store: open = 9 close = 9
def hours: return hours ("We're open from {} to {}.").format(self.open, self.close)
For the life of me, I can't understand why this code isn't working!
