Add Method hours

class Store: open = 9 close = 8

def hours(hours): return.hours("We're open from 9 am to 8 pm.")

OR def hours(hours): return.format("We're open from 9 am to 8 pm.")

I get error.

method.py 
class Store:
  open = 9
  close = 8

  def hours(hours):
  return.hours("We're open from 9 am to 8 pm.")


OR 
def hours(hours):
  return.format("We're open from 9 am to 8 pm.")

Hello Ellie,

Remember that your hours method needs to have the self parameter. The reason for this is because when an instance ( or a Shop object in this case) calls on the hours method, this will ensure that that object is calling on the hours method. After doing that you simply return a string then use the dot notation to access the format method. You need to then pass in the objects open and close properties into the format method. The final result should look like this:

class Store:
  open = 9
  close = 8

  def hours(self):
    return "We're open from {} to {}.".format(self.open, self.close)
