Creating all possible ways of a boolean array of size n in Python3

Question

I want to create a list of all possible booleans with a given length n, using Python 3.

# suppose n = 2
# the expected output should be
output = [[0, 0], [0, 1], [1, 0], [1, 1]]

In my real application, n is never larger than 10.

A similar post is here but for Java.

Could you please show me how to do it in Python 3? Thanks in advance.

A good opportunity to leverage itertools:

def boolean_combinations(n):
    return [
        *itertools.product(
            *[range(2) for _ in range(n)]
    )]
