Inside a method, you must explicitely use the instance
(conventionally (and in your case) names "self") to access an object
attribute. In your example, this means, you must use "self.time = '6:30'
not "time" alone (you did this in the "__init__" method).
If you are using "time" (without the "self." prefix), you are defining
a new local variable.
In this regard, Python differs from many object oriented languages.
