Problem with Workspace?

Question

I can't tell why this won't pass... 
I do notice that 'open' isn't colored like 'close' is, leading me to suspect that 'open' is a python keyword that might be screwing with this challenge?
Thanks in advance for any help!
```method.py
class Store:
  open = 9
  close = 4
  def hours(self):
    return "We're open from {} to {}.".format(open, close)
```

Hey hey, you're correct that open() is a keyword in python.  It's a built-in function -- check it here (https://docs.python.org/3.4/library/functions.html) -- but that won't interfere with the challenge.
Looks like you've called self in the hours function, so wouldn't you also call self on open and close in the format function?  i.e., self.open and self.close?  Perhaps??

No problem man!  Yeah, I had to spend an evening wrapping my head around using self properly.  I like the way you're thinking about it though; if it were that way, it'd clean up a lot of extra self-s in the code.  I found this stackoverflow (http://stackoverflow.com/questions/2709821/what-is-the-purpose-of-self-in-python) to be handy in understanding self, particularly the answer with the arrows.

Oh man... I thought that once 'self' was passed into the method, the rest of the code within that method would know where to look. 
Thanks so much!
