An alternative solution for Q.82

82. Compute a matrix rank (★★★)
    hint: np.linalg.svd

# Author: Stefan van der Walt

Z = np.random.uniform(0,1,(10,10))
U, S, V = np.linalg.svd(Z) # Singular Value Decomposition
rank = np.sum(S > 1e-10)
print(rank)

numpy.linalg.matrix_rank Doc provides an alternative way to compute matrix rank.

The alternative solution will be:

from numpy.linalg import matrix_rank

Z = np.random.uniform(0,1,(10,10))
print(matrix_rank(Z))

My bad. I've updated Q.82 in my last comment.

Should I close this issue then?
