HackerRank Correctness and the Loop Invariant solution

In this HackerRank Correctness and the Loop Invariant problem, In the InsertionSort code below, there is an error. Can you fix it? Print the array only once, when it is fully sorted.

Problem solution in Python programming.

def insert_sort(A):
	m = len(A)
  
	for x in range(1,m):
		k = A[x]
		j=x
		while(j>0 and A[j-1]>k):
			A[j] = A[j-1]
			j-=1
      
		A[j]=k
        
	return A

i = int(input())
N = [int(c) for c in input().split()]
N = insert_sort(N)


for a in N:
  print(a, end=" ")
