Python bubble sort

Bubble Sort:

There is a set of numbers to be sorted, and we are here to sort the numbers in small to large order.
Compares the first number (40) to the second number (20), > 20, the swap position. The second number (40) compares to the third number (30), and >30, the swap position. The third number (40) is compared to the fourth number (10), and >10, the swap position. Compares the fourth number (40) to the fifth number (50), <50, and does not move. In this way, the top number is the largest number, and we just need to sort the next four numbers.
