Create matrix of random integers in range by step using Python

I would like to create a matrix (rows/columns determined by user) of random integers in a range by step. I have been trying to get step into random.random_integers but it has not been working for me. Example output:

Size 3x4, range 22-37, step 2:

[[26 22 32 28]

[24 30 26 22]

[36 34 22 36]]
