please explain the steps

Given the elements of a 3 3 matrix as the nine variables a11, a12, . . . , a33, produce a string representation of the matrix using formatting methods, (a) assuming the matrix elements are (possibly negative) real numbers to be given to one decimal place; (b) assuming the matrix is a permutation matrix with integer entries taking the values 0 or 1 only. For example,

>>> print(s_a)

[ 0.0 3.4 -1.2 ]

[ -1.1 0.5 -0.2 ]

[ 2.3 -1.4 -0.7

] >>> print(s_b)

[ 0 0 1 ]

[ 0 1 0 ]

[ 1 0 0 ]
