bubble sort sort in python code example

Example 1: python bubble sort

def bubbleSort(arr): 
    n = len(arr) 
  
    # Traverse through all array elements 
    for i in range(n-1): 
    # range(n) also work but outer loop will repeat one time more than needed. 
  
        # Last i elements are already in place 
        for j in range(0, n-i-1): 
  
            # traverse the array from 0 to n-i-1 
            # Swap if the element found is greater 
            # than the next element 
            if arr[j] > arr[j+1] : 
                arr[j], arr[j+1] = arr[j+1], arr[j] 
  
# Driver code to test above 
arr = [64, 34, 25, 12, 22, 11, 90] 
  
bubbleSort(arr)

Example 2: bubble sort technique in python

def bubbleSort(arr): 
    n = len(arr) 
  
    # Traverse through all array elements 
    for i in range(n-1): 
    # range(n) also work but outer loop will repeat one time more than needed. 
  
        # Last i elements are already in place 
        for j in range(0, n-i-1): 
  
            # traverse the array from 0 to n-i-1 
            # Swap if the element found is greater 
            # than the next element 
            if arr[j] > arr[j+1] : 
                arr[j], arr[j+1] = arr[j+1], arr[j] 
  
# Driver code to test above 
arr = [10, 51, 2, 18, 4, 31, 13, 5, 23, 64, 29] 
  
bubbleSort(arr)
print ("Sorted array is:") 
for i in range(len(arr)): 
    print ("%d" %arr[i]),
