Bubble Sort Algorithm Explained (Full Code Included) – Python Algorithms Series for Beginners

17
67



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]))

  1. Fell in love with the way, you explain things. It's easy to grasp. Please keep posting the videos. (if possible , could you please post a video on recursion and how to apply it in different scenarios). Thank You

  2. If there are flowchart, tracetable and pseudocode inclding in this video as well, it would be very helpful for some students who study computing foundation.

  3. sir it is inot working when i am running this programme , it returns me that bubble sort is not defined it"s my doubt and please sir clear it ASAP!

  4. Great video but I would like to know if its possible to place in variables in the algorithm to sort as I would like to create a leaderboard where it shows the username of the player and the score they got in the end

  5. Really a fan of your videos. Well presented every time and it keeps getting better and better. Keep up the good work. This series seems very interesting. Cheers!

  6. Hey, Derrick nice video as always, I am just playing all your videos looking for ideas for graduation final assignment work for my college. Maybe do you have any? It could be anything IT & finance related
