How do I create a new object for each class instance?

Please look at the code snippet below, I asked the question below

class SAMPLES:
    x = np.zeros(10)

    def __init__(self, k, value):
        self.x[k] = value


a = SAMPLES(0, 9)
b = SAMPLES(0, 10)
print(a.x[0])
print(b.x[0])

OUTPUT:

10
10

But the output must be:

9
10

How should I solve this problem?

>Solution :

Declare x within the __init__ method.

class SAMPLES:
    def __init__(self, k, value):
        self.x = np.zeros(10)
        self.x[k] = value


a = SAMPLES(0, 9)
b = SAMPLES(0, 10)
print(a.x[0])
print(b.x[0])
