Which part of the loop is it going through in this class frame?

It didn't. You have misunderstood what is happening. Let's go though it 
bit by bit:

The "class" statement declares a new class, called "Clock", which 
inherits from the built-in class "object".

[Aside: some people describe "object" as a "type" rather than a class. 
There are some differences in meaning between type/class in computer 
science, and in Python 2 they are slightly different things, but in 
Python 3 you can consider class and type to be synonyms.]

So object is not a parameter, it is a superclass. This tells Python that 
your Clock class is a subclass of object.

The initialiser __init__ method is special, because it defines the 
signature for calling the class. So when you say:

    clock = Clock("5:30")


Python creates a new Clock instance, and calls __init__ and passes "5:30" 
as the *time* parameter.

(I have glossed over some technical details and complexities.)

The thing to remember is that when you create a new instance by calling 
the class Clock(...), your arguments have to match the __init__ method.
