Neighbours in an array

[MattaFX]

Hi everyone,

I've got the following problem: 

Example: 
If the original Input is:

[[0 0 0 0 0 0 0 1]
[0 0 0 0 0 0 0 0]
[0 0 0 0 0 0 0 0]
[0 1 1 1 0 0 0 0]
[0 0 0 0 0 0 0 0]
[0 0 0 0 0 0 0 0]]

The result should be:

[[0 0 0 0 0 0 1 0]
[0 0 0 0 0 0 1 1]
[1 2 3 2 1 0 0 0]
[1 1 2 1 1 0 0 0]
[1 2 3 2 1 0 0 0]
[0 0 0 0 0 0 0 0]]

I started as following:

from numpy import zeros

inp = zeros(shape=(6,8),dtype=int)
inp[0,7]=1
inp[3,1:4] = 1

inp_new = 0*inp
print(inp)

P = inp.shape[0]
Q = inp.shape[1]

print(P, Q)

for p in range(1,P-1):
    for q in range(1, Q-1):
        inp_new[p,q] = inp[p+1, q]+inp[p-1, q]+ inp[p, q+1] + inp[p, q-1]+inp[p+1,q+1]+inp[p+1,q- 1]+inp[p+1,q-1]+inp[p-1,q- 1]

But something is wrong, especially with the first and the last columns and rows. 

Thanks for any help! :)
