How we can solve it general

Python3.6

# We have given a matrix and position of square N*N submatrix,
# We have to rotate that submatrix by 90 degree in clockwise direction
# And, then print whole matrix
# For example, Input matrix is,
# 1 2 3 4
# 5 6 7 8
# 9 10 11 12
# 13 14 15 16
# Position (x, y) = (1, 1) and Value of N = 3
# Output is,
# 1 2 3 4
# 5 14 10 6
# 9 15 11 7
# 13 16 12 8

What I have tried:

I have tried in python but it is applicable only for when x and y are same.

def rotate_submat_90_clk(A, x, y, N):
    for i in range(N//2):
        for j in range(i, N-i-1):
            temp = A[i+y][j+x]
            A[i+y][j+x] = A[N-j-1+x][i+y]
            A[N-j-1+x][i+y] = A[N-i-1+y][N-j-1+x]
            A[N-i-1+y][N-j-1+x] = A[j+x][N-i-1+y]
            A[j+x][N-i-1+y] = temp
    for i in range(len(A[0])):
        print(A[i])
