Great thanks for BartoszKP pointed out that data set defined in Python class behaves like static in other language. I used the code below to verify this:

class TwoDimList:
    _Val = [ [ i for i in range(6) ] for j in range(6)]

    def __init__(self) :
        for d1 in range(6):
            for d2 in range(6):
                self._Val[d1][d2] = random.randint(0, 9)

    def printVal(self) :
        print(self._Val)

b1.printVal()
b2.printVal()
