Bubble Sort is a simple sorting algorithm that repeatedly swaps two adjacent elements through iterations through the list length to create a sort list.

The Bubble sort algorithm is one of the simplest algorithms to learn in computer science and is a great starting point to learn tougher algorithms.

In this one we'll cover how to implement the bubble sort algorithm using python programming.

Full code from the video:
def bubble(list_a):
indexing_length = len(list_a) - 1 #SCan not apply comparision starting with last item of list (No item to right)
sorted = False #Create variable of sorted and set it equal to false

while not sorted: #Repeat until sorted = True
sorted = True # Break the while loop whenever we have gone through all the values

for i in range(0, indexing_length): # For every value in the list
if list_a[i] #"Angled brackets not allowed in Youtube Description :( list_a[i+1]: #if value in list is greater than value directly to the right of it,
sorted = False # These values are unsorted
list_a[i], list_a[i+1] = list_a[i+1], list_a[i] #Switch these values
return list_a # Return our list "unsorted_list" which is not sorted.


print(bubble([4,8,1,14,8,2,9,5,7,6,6]))
