Object-oriented Python example

What is wrong with this code? It fails to pass the test however when I run it in the Python 2.7 interpreter, it works fine.

class Store(object):
    open = 9
    close = 16

    def hours(self):
        return "We're open from {0} to {0}".format(self.open,self.close)

Hi Tim,

You have a couple of problems with your return string which is causing the issues.

  1. You have set {0} when instead you just want {} as you only need to define alphanumeric values when unpacking data
  2. You have left off the full stop at the end of the string.
return "We're open from {} to {}.".format(self.open, self.close)

Hope that helps.

You don't need to add object to your Store declaration, as it's implied. So you can just do this:

class Store():
    open = 9
    close = 16

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

store = Store()
print(store.hours())

Thanks guys.

@Ryan, is object implied for only Python 3? I'm working almost completely in Python 2.7.

And if it is implied, should I not be able to do simply <code>class Store:</code>?

Durrr, you're right, sorry. It'd just be:

class Store:

Sorry!
