r = 2
e = 3

sup = []

for i in range(n):
    sup1 = []
    for c

You can use numpy to directly get the random matrix of desired size with values in a given range.

>>> numpy.random.randint(low = 0, high = 200, size=(2, 4))
array([[ 75,  21, 132,  90],
       [112,  11, 104, 114]])

>>> r = 2
>>> n = 1
>>> numpy.random.randint(low = 0, high = 200, size=(r, n))
array([[94],
       [51]])
