So, yes, they do. Defining `__iter__()` is now the preferred way of making instances of a class iterable. So even though having `__getitem__()` is sufficient, most iterables will have `__iter__()` defined
Not sure I follow the question fully. But yes, when you create a string such as "hello", you're effectively creating an instance of the str class, so it's a shorthand for str()
The str class will then have whatever special methods it needs to give it its properties, such as __iter__() to make it iterable, and so on
In this series, I'll be looking at other categories of data structures so I'll be exploring more of these special (dunder) methods that give objects these properties, such as __iter__() to make an iterable
Was a side comment. Like i guess not all default types implement __iter__ like ints for example. For __iter__ to be added to strs, it has to be added at some point by the VM. Must look into this process.
So, do strings implement __iter__?
>>> some_string = "hello"
>>> some_string.__iter__

So, since everything is a class in Python, some behaviors get added at some point for default literals. Must look into this at the CPython level
