In Day 11 of our Python OOP series, we dive into one of the most powerful and misunderstood concepts in programming — Polymorphism.
This lesson is where OOP stops being theory and starts becoming real-world design.
You will learn:
What polymorphism actually means in practical terms
How method overriding works at runtime
How one function can work with many different objects
How to design systems using interface-style thinking
How Python uses Duck Typing for flexible, clean code
Why professionals avoid long if-else chains
How to write extensible, future-proof programs
Through clear examples like:
Shapes calculating area
Payment gateways (UPI, Card, Net Banking)
Export systems (PDF, JSON, Excel)
Logger and service-style architectures
You’ll understand how one method call can produce many behaviors and how to let objects decide what they do instead of controlling everything with conditions.
By the end of this video, you won’t just “know” polymorphism —
you’ll think in polymorphism.
This is the day you move from writing student code to writing developer-grade OOP.
