Python namedtuple, deque & ChainMap Explained | Collections Module Lecture 3
In this video, I explain three powerful types from the Python collections module: namedtuple, deque, and ChainMap in a simple and easy-to-understand way.
You will learn:
What namedtuple is and how it helps create structured and readable data
How to access tuple elements using names instead of an index
Real-world example using stock data
What a deque (Double-Ended Queue) is and how it allows fast operations from both ends
How to use a deque for adding and removing elements efficiently
Use cases like a queue, a stack, and a recent trades system
What ChainMap is and how it combines multiple dictionaries into one view
How updates work in ChainMap
Practical example using multiple stock dictionaries
Mini Challenge:
Store stock data efficiently using:
namedtuple for structured data
deque for managing recent trades
ChainMap for combining stock data
This is part of my Python learning journey, where I teach real-world Python concepts step by step.
