Python init, Iterator & next Explained | Python Object Iteration Tutorial
Hey Everyone,
Welcome back to SummarizedAI!
Here’s what we’ll cover:
_init_ – How constructors initialize an object’s attributes when it’s created 🔧
Iterators – How to traverse through elements of a collection (like lists, tuples, or custom objects) one by one.
__iter__() – Returns the iterator object and tells Python where to start iteration.
__next__() – Returns the next item in the sequence; raises StopIteration when done.
We’ll also see how Python’s for loop internally calls __iter__() and __next__() to iterate through collections seamlessly.
By the end of this video, you’ll understand how to create and use iterators effectively in Python.
