Solve this problem, I will be very grateful

Должно выйти так

 

Нужно найти матрицу инцидентности графа

 

a = [[0,0,0,0],[0,0,0,0],[0,0,0,0],[0,0,0,0],[0,0,0,0]]

mas = [[1, 2], [3, 4], [2, 3], [1, 4]]

for i in range(4):
a[mas[i][0]-1][i] = -1
a[mas[i][1]-1][i] = 1

for i in a:
print(i)

Code

a = [[0,0,0,0],[0,0,0,0],[0,0,0,0],[0,0,0,0],[0,0,0,0]]



mas =  [[1, 2], [3, 4], [2, 3], [1, 4]]



for i in range(4):

    a[mas[i][0]-1][i] = -1

    a[mas[i][1]-1][i] = 1



for i in a:

    print(i)

Пасиб, я сделал по-дургому. Хуйня получиласб, главное что работает.

v = 0
for i in range(k):
array.append([])
for j in range(z):
array[i].append(0)
while True:
for x, y in mat:
if x == y:
array[x-1][y-1] = 2
v = v + 1
else:
array[x-1][v] = -1
array[y-1][v] = 1
v = v+1
break

Code

v = 0

    for i in range(k):

        array.append([])

        for j in range(z):

            array[i].append(0)

    while True:

        for x, y in mat:

            if x == y:

                array[x-1][y-1] = 2

                v = v + 1

            else:

                array[x-1][v] = -1

                array[y-1][v] = 1

                v = v+1

        break
