Pls Use Python

Using NumPy, write the program that determines whether the A=({{1, 5, -2}, {1, 2, -1}, {3, 6, -3}}) matrix is ​​nilpotent. 

Itro: Nilpotent Matrix: A square matrix A is called nilpotent matrix of order k provided it satisfies the relation, Ak = O and Ak-1≠O where k is a positive integer & O is a null matrix of order k and k is the order of the nilpotent matrix A .

The following picture is an example of the intro:

 

Ps: Please also explain step by step with " # "

Hence, the matrix A is nilpotent of order 3.
