How can I implement sorting algorithms in Python?

You can implement various sorting algorithms in Python, such as bubble sort, quicksort, and mergesort. Which one are you interested in?

Let's start with bubble sort. Can you show me the code?

Sure! Here's a simple implementation of bubble sort in Python:

def bubble_sort(arr):
    n = len(arr)
    for i in range(n):
        for j in range(0, n-i-1):
            if arr[j] > arr[j+1]:
                arr[j], arr[j+1] = arr[j+1], arr[j]
    return arr

# Example usage:
arr = [64, 34, 25, 12, 22, 11, 90]
sorted_arr = bubble_sort(arr)
print(sorted_arr)

What is the time complexity of bubble sort?

The time complexity of bubble sort is O(n^2) in the worst and average cases, where n is the number of items being sorted.

Are there more efficient sorting algorithms?

Yes, algorithms like quicksort and mergesort are more efficient, with average time complexities of O(n log n). Would you like to see an example of one of those?
