Operator Overloading in Python | Python OOP Series #11
How does Python know what to do when you write:
10 + 20
or
"Hello" + "World"
The answer is Operator Overloading.
In this video, you'll learn how Python maps operators to dunder methods and how you can define custom behavior for operators in your own classes.
We'll cover:
• What Operator Overloading is
• How Python handles a + b
• The __add__() dunder method
• Building a Money class
• Creating custom operator behavior
• Real-world use cases
• Scientific computing applications
• Financial software examples
By the end of this lesson, you'll understand how libraries like NumPy and financial applications use operator overloading to create clean, intuitive APIs.
