bubble sort in python using while code example

Example 1: bubble sort python

def bubbleSort(lis):
    length = len(lis)
    for i in range(length):
        for j in range(length - i):
            a = lis[j]
            if a != lis[-1]:
                b = lis[j + 1]
                if a > b:
                    lis[j] = b
                    lis[j + 1] = a
    return lis

Example 2: bubble sort python

def bubble(st):
    for i in range(len(st),1,-1):
        for j in range(0,i-1):
            if st[j]>st[j+1]:
                st[j],st[j+1]=st[j+1],st[j]
            else:
                pass
    print(st)
bubble([64, 34, 25, 12, 22, 11, 90] )
