Answer to Question #200065 in Python for Narendra

Question

M, N = list(map(int,input().split()))
matrix = []
for i in range(M):
	z = [int(x) for x in input().split()]
	matrix.append(z)
K = int(input())
values = []
k =0
l =0
while (((N - k) > 0) and ((M - l) > 0)) and ((N - k)*(M-l)) > K:
	for i in range(k,N):
		values.append(matrix[k][i])
	for j in range(l+1,M):
		values.append(matrix[j][N-1])
	for i in range(N-2,k-1,-1):
		values.append(matrix[M-1][i])
	for j in range(M-2,l,-1):
		values.append(matrix[j][k])
	values = values[-K:] + values[:-K]
	c = 0
	for i in range(k,N):
		matrix[k][i] = values[c]
		c += 1
	for j in range(l+1,M):
		matrix[j][N-1] = values[c]
		c += 1
	for i in range(N-2,k-1,-1):
		matrix[M-1][i] = values[c]
		c += 1
	for j in range(M-2,l,-1):
		matrix[j][k] = values[c]
		c += 1		
	values = []
	k += 1, l += 1, M -= 1, N -= 1
for i in matrix:
  print(i)
we are getting when input is 
4 4
1 2 3 4 
5 6 7 8 
9 10 11 12 
13 14 15 16 
3
but the output is: 
9  10  11  
5  6  12  
1  7  8  
when input is:
3 4
1 2 3 4 
5 6 7 8 
9 10 11 12 
2
