    import numpy as np
N = int(input())
A = np.array([input().split() for _ in range(N)],float)
print(round(np.linalg.det(A),2))

    import sys import numpy as np

    As usual with HackerRank problems, N is unnecessary.

    However, this time I felt like using it as an example

    of checking the input.

    print([(N := int(input())),

    np.linalg.det(np.loadtxt(sys.stdin.readlines(), float)[:N, :N]).round(2)][1])****

    import numpy as np

n = int(input())
a = [list(map(float, input().split())) for _ in range(n)]

det = np.linalg.det(a)
print(round(det, 2))

    My compact solution…

    import sys
import numpy as np

# As usual with HackerRank problems, `N` is unnecessary.
# However, this time I felt like using it as an example
# of checking the input.

print([(N := int(input())),
    np.linalg.det(np.loadtxt(sys.stdin.readlines(), float)[:N, :N]).round(2)][1])
