python function to sort a list

Title: A Comprehensive Guide to Sorting Lists in Python Using the sorted() Function
Introduction:
Sorting elements in a list is a common operation in programming, and Python provides a built-in function called sorted() to simplify this task. This tutorial will guide you through the usage of the sorted() function in Python to effectively sort lists.
1. Understanding the sorted() Function:
The sorted() function is a versatile tool for sorting various iterable objects, including lists. It takes an iterable (e.g., a list) as its argument and returns a new sorted list without modifying the original list.
2. Basic Usage:
Let's start with a simple example. Suppose you have an unsorted list of numbers:
To sort this list in ascending order, use the sorted() function:
This will output:
The original list numbers remains unchanged.
3. Sorting in Descending Order:
To sort the list in descending order, you can use the reverse parameter of the sorted() function:
This will output:
4. Custom Sorting with the key Parameter:
You can customize the sorting order by using the key parameter, which allows you to specify a function that calculates a value for each element, and the sorting is based on these values. For example, let's sort a list of strings based on their lengths:
This will output:
