how to randomize the component values ​​of the matrix in PYTHON

I have a matrix (3,3) like this:[[1, 0, 1]
                                 [0, 1, 0]
                                 [1, 1, 0]]

How can i random the value of position(2,2) with the range is around its current value( for example the value of (2,2)=1 and i want it to random in range 0 and 2.
