Who can help me?

Question

W[0].insert(0, 0)

W[1].insert(1, 0)

W[2].insert(2, 0)

to 7

Do you know a way by for or while loops to
Write these codes in a easier way?

Answer 1

def hopfield1(spin) :
Num=len(spin)
W=[[0]*Num for i in range(0,Num)]
...

W had 4 copies of the same list (listac). Solved now.

Answer 2

Please link your complete code here. This makes it much more easier to help. Thank’s!

Answer 3

What is 'W'? Is it a 2D array?

Answer 4

Yes it's 2D

Answer 5

...and how is it meant to look before and after these lines?

Answer 6

is:

for i in range(8):
W[i].insert(i, 0)

...enough?

Answer 7

def hopfield1(spin) :
Num=len(spin)
listac=[0 for i in range(0,Num) ]
W=[listac for i in range(0,Num)]
for i in range(0,Num):
for j in range(0,Num):
if i!=j:
W[i][j] =spin[i] *spin[j]
else:
W[i][j] =0
print(W)
return
hopfield1([-1,1,-1,1] )
I wanted this result

W=[[0,-1,1,-1],[-1,0,-1,1],[1,-1,0,-1],[-1,1,-1,0]]

EX.
W[2][3]=spin[2]*spin[3]
W[2][2]=0

Answer 8

It's my code

Answer 9

But the real result isn't like this

Answer 10

Thank you very much.

Answer 11

While I < 8 : w[I].insert(I,0)
