Insertion Sort - Part 2

    I did about the same, but using a sentinel at the front of the array:

    n, amin = int(input()), -10**4
A = [2*amin] + list(map(int, input().split()))
for j in range(2, n+1):
    i, a = j, A[j]
    while a < A[i-1]:
        A[i] = A[i-1]
        i -= 1
    A[i] = a
    print(*A[1:])
