Скачать или смотреть Example of Iterator in Python for Printing 1 3 | Custom Iterators

Want to truly understand how Python iterators work under the hood? In this short and powerful video, we explain how to create a custom iterator that prints specific numbers — in this case, 1 and 3 — to teach you the essentials of Python’s _iter_ and _next_ methods.

This video is a must-watch for beginners, computer science students, and anyone preparing for interviews or coding exams. Dr. Sourav Sir’s Classes walks you step by step through building your own iterator class to control custom output sequences with ease.

🧠 What You’ll Learn in This Video:

What is an iterator in Python

Difference between iterables and iterators

How to define _iter_ and _next_ methods

Writing a custom iterator that prints 1 and 3 only

Internal mechanism of Python's for loop using iterators

How Python handles StopIteration exception

Application of iterators in data streaming and lazy loading

🎯 Why Are Iterators Important?
✔️ Enables lazy evaluation
✔️ Great for memory-efficient coding
✔️ Powerful for custom sequence logic
✔️ Core to Python’s for loops, generators, and comprehensions
✔️ Essential for data structures, web scraping, and I/O streaming
