L 34: INTRODUCTION TO FUNCTIONS IN PYTHON | FUNCTION IN PYTHON | PYTHON COURSE FOR BEGINNERS смотреть онлайн

In Python, a function is a group of related statements that performs a specific task.
Functions help break our program into smaller and modular chunks. As our program grows larger and larger, functions make it more organized and manageable.
Furthermore, it avoids repetition and makes the code reusable.
function definition that consists of the following components.
1. Keyword def that marks the start of the function header.
2. A function name to uniquely identify the function. Function naming follows the same rules of writing identifiers in Python.
3. Parameters (arguments) through which we pass values to a function. They are optional.
4. A colon (:) to mark the end of the function header.
5. Optional documentation string (docstring) to describe what the function does.
6. One or more valid python statements that make up the function body. Statements must have the same indentation level (usually 4 spaces).
7. An optional return statement to return a value from the function.

The return statement:
The return statement is used to exit a function and go back to the place from where it was called.
This statement can contain an expression that gets evaluated and the value is returned. If there is no expression in the statement or the return statement itself is not present inside a function, then the function will return the None object.
