What is the protocol for iterable objects in Python?

In Python, the iterable protocol refers to the concept that if an object implements the __iter__() method, then it is considered iterable. Iterable objects allow for iterating through their elements using a for loop. When iterating through an iterable object using a for loop, it actually calls the object’s __iter__() method to obtain an iterator object, and then retrieves elements one by one using the iterator object’s __next__() method. Therefore, an object that implements the __iter__() method adheres to the iterable protocol.
