Class and method Test

class Store:
  open = '9'
  close = '4'

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

I get the message "hours not defined" or "try again" i've tried typing the the opening hours like: open = 9, open = '9' i'm stuck i'm doing it just as in the video..i think

Hi Isaac,

I checked the challenge and it doesn't seem to care whether you store the hours as integers or strings. Based on the instructions it looks like they should be stored as integers without quotes.

Your real issue is the return statement.

string is a temporary local variable that you created to store the output string. It's not an attribute of the class so you wouldn't need to access it using self

On the other hand, open and close are attributes of the class and would need to be accessed using self

class Store():
  open = 9
  close = 4

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

thanks!!!

You're welcome.

To save a line of code you could even skip the my_string variable and return the string directly.

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