scope with .format

I don't understand the scope of open and close. What am I doing wrong?

method.py 
class Store:
    open = 6
    close = 8
    def hours():
        return str"We're open from {} to {}.".format(open, close)

.format is a function which replaces every {} in a string a variable that you pass through the function. The variables must be passed through the function in the intended order within the string.

So here you are having an error because you forgot your ( and ) for the str function. The corrected code would be:

class Store:
    open = 6
    close = 8
    def hours():
        return str("We're open from {} to {}.".format(open, close))

:point_right: You don't need "str", but you might need "self".

Your return statement is formatting a string, which will return a string, so you don't need the "str" function at all.

But you probably do want to have hours use "self" as an argument, and then use "self" to prefix the names of the attributes being passed to format.
