Python 2d array loop

It might be stupid question but I'm starting with python and I have no clue how to write it.

So I want to print this table in loop like on the screen and then I want it to be usable but It's hard for me to write it down (look on screen pls):

table = [print([random.randint(0,1) for x in range(10)]) for y in range(10)]
a = table
print(a)

console output

The values are printed using the print inside the list. But the method print return nothing, None, so you're saving 10 None in the outer list

table = [[random.randint(0, 1) for x in range(10)] for y in range(10)]
for row in table:
    print(row)
a = table
print(a)

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