Implementation of Insertion Sort in Python

Insertion Sort builds the final sorted array (or list) one item at a time. It is much less efficient on large lists than more advanced algorithms such as quicksort, heapsort, or merge sort.

def insertion_sort(arr):
    
    # For every index in array
    for i in range(1,len(arr)):
        
        # Set current values and position
        currentvalue = arr[i]
        position = i
        
        # Sorted Sublist
        while position > 0 and arr[position-1] > currentvalue:
            
            arr[position]=arr[position-1]
            position = position-1

        arr[position] = currentvalue
arr =[3,5,4,6,8,1,2,12,41,25]
insertion_sort(arr)
print(arr)

[1, 2, 3, 4, 5, 6, 8, 12, 25, 41]
