HackerRank Python - Linear Algebra

The NumPy module also comes with a number of built-in routines for linear algebra calculations. These can be found in the sub-module linalg.

linalg.det

The linalg.det tool computes the determinant of an array.

linalg.eig

The linalg.eig computes the eigenvalues and right eigenvectors of a square array.

linalg.inv

The linalg.inv tool computes the (multiplicative) inverse of a matrix.

import numpy as np

np.set_printoptions(legacy='1.13')

n = int(input())
array = np.array([input().split() for _ in range(n)], float)
print(np.linalg.det(array))
