python – How to randomly get 0 or 1 every time?

The problem is that your code generates a single value and then prints it repeatedly. A simplified version of the problem would be this:

k = random.randint(0, 1) # decide on k once
for _ in range(n):
    print(k) # print k over and over again

This will generate k, then print it n times, but what you want is to generate a new value to print each time

for _ in range(n):
    k = random.randint(0, 1) # decide on a k each time the loop runs
    print(k)

You can generate the matrix itself using a nested list comprehension (which may be more than you want to know at this point, but worth showing)

[[random.randint(0, 1) for _ in range(n)] for _ in range(n)]

the inner part [random.randint(0, 1) for _ in range(n)] will give you n values in the range 0-1. nesting that in another comprehension gives you n of those.

from random import randint
n = int(input (Enter an interger number:))
matrix = (
    [str(randint(0, 1)) for _ in range(0, n)] for _ in range(0, n)
)
for row in matrix:
    print .join(row)

FYI. check this documentation about list comprehension

def printMatrix(n):

        return n + 0


def main():

     n = int(input (Enter an interger number:))

    matrix = ([str(randint(0, 1)) for _ in range(0, n)] for _ in range(0, n))

    for row in matrix:

         print( .join(row))

main()
