Study Notes

Functions in Python

A function is a block of code that can be executed multiple times from different parts of a program, allowing for modularity and reusability of code.
Functions help to organize code in a logical and structured way, making it easier to maintain and update.

Importance of Functions

Functions are helpful in programming because they enable code reuse, reduce repetition, and make the code more modular and flexible.
They also improve code readability by breaking down a complex program into smaller, manageable chunks.

Built-in Functions

Python has a range of built-in functions that can be used to perform specific tasks, such as mathematical operations, string manipulation, and data structure operations.
Examples of built-in functions include len(), range(), print(), and sum().

Code Readability and Reusability

Functions contribute to code readability by allowing developers to focus on the logic of the program without being overwhelmed by the details of implementation.
They also promote code reusability by enabling developers to write code that can be used in multiple contexts, reducing the need to duplicate code.

User-Defined Functions

The primary purpose of user-defined functions in Python is to create custom functionality that can be tailored to specific needs and requirements.
User-defined functions enable developers to extend the functionality of Python beyond what is provided by built-in functions.
