How to make a 2D array with manual input?

Question

Python

I recently started learning Python and ran into a problem - I need to write a program that takes a rectangular matrix as a sequence of lines as input, ending with a line containing only the string "end".
Tried to implement something, in the end nothing comes out. I do not understand how to make an empty two-dimensional list filled line by line.

list = 
cnt = 0
while 0 == 0:
    cw = [int(i) for i in input().split()]
    if 'end' in cw:
        break
    list[cnt] = cw
    cnt += 1
for i in range(len(list)):
    for j in range(len(list[i])):
        print(j, end=' ')
    print()

According to your style:

L = []
while True:
    S = [i for i in input().split()]
    if 'end' in S:
        break
    N = [int(i) for i in S]
    L.append(N)
print(L)
