Insertion sort program in python

# insertionsort() function to implement insertion sort
def insertionsort( aList ):
 for i in range( 1, len( aList ) ):
   tmp = aList[i]
   k = i
   while k > 0 and tmp < aList[k - 1]:
       aList[k] = aList[k - 1]
       k -= 1
   aList[k] = tmp

# Example to sort an array using insertion sort
A=[44,21,3,88,12,65,4]
# Calling insertionsort() function
insertionsort(A)
# printing the sorted array
print A
