Lesson 17 of 20 · Abstraction
Abstraction — Part 6
Hide details. Your own abstractions. This is part 6 of 20.
What you'll learn
You will learn that abstraction means using things by name without needing to know the details inside.
Steps
- 1greet('Alex') prints 'Hello, Alex'. You don't need to know HOW print() draws text on screen — you just use it. That's abstraction!
- 2Abstraction means using something by name without knowing every detail inside. You use a TV remote without knowing its circuits.
- 3The greet() function takes a 'name' parameter — different input, same behavior. greet('Alex') → Hello, Alex. greet('Sam') → Hello, Sam.
- 4As you build bigger programs, you'll create your own functions to hide complexity. This keeps code clean and easy to understand.

- Abstraction
- Using something by its name without needing to know every detail of how it works.
