Sorting is an essential concept in programming that allows you to arrange a collection of elements in a specific order. In this article, we’ll explore the process of sorting a list of numbers in Python, covering both built-in functions and custom implementation.

Definition of Sorting:

Sorting refers to the process of arranging a list of elements in a particular order, such as alphabetical or numerical. This is a fundamental concept in programming that has numerous applications in various fields, including data analysis, science, and engineering.

Step-by-Step Explanation:

To sort a list of numbers in Python, you can use either built-in functions or custom implementation. Here’s a step-by-step guide to both approaches:

Using Built-In Functions

Python provides an efficient way to sort lists using the sort() function. Here’s how you can use it:

numbers = [64, 34, 25, 12, 22, 11, 90]
numbers.sort()
print(numbers)

Output: [11, 12, 22, 25, 34, 64, 90]

The sort() function sorts the list in ascending order by default. You can also sort the list in descending order by passing the reverse=True argument:

numbers = [64, 34, 25, 12, 22, 11, 90]
numbers.sort(reverse=True)
print(numbers)

Output: [90, 64, 34, 25, 22, 12, 11]

Custom Implementation

If you want to implement a sorting algorithm from scratch, you can use the Bubble Sort algorithm. Here’s an example implementation:

def bubble_sort(numbers):
    n = len(numbers)
    for i in range(n-1):
        for j in range(n-i-1):
            if numbers[j] > numbers[j+1]:
                numbers[j], numbers[j+1] = numbers[j+1], numbers[j]
    return numbers

numbers = [64, 34, 25, 12, 22, 11, 90]
sorted_numbers = bubble_sort(numbers)
print(sorted_numbers)

Output: [11, 12, 22, 25, 34, 64, 90]

The Bubble Sort algorithm works by repeatedly iterating through the list and swapping adjacent elements if they are in the wrong order.

Code Explanation:

• The sort() function is a built-in Python function that sorts a list of elements in ascending or descending order.
• The bubble_sort() function implements the Bubble Sort algorithm, which sorts a list by repeatedly iterating through it and swapping adjacent elements if they are in the wrong order.
• In both examples, we create a list of numbers and sort them using either the sort() function or the custom bubble_sort() implementation.
