How many natural numbers greater than 15 and less than 40 are divisible by 3?
15 1 [OP_ADD] 40 1 [OP_SUB] 1 [OP_LIST_ARANGE] 3 [OP_LIST_DIVISIBLE] [OP_LIST_LEN]

var_f = var_d - var_e
var_g = 1
list_a = [i for i in range(var_c, var_f + 1, var_g)]

var_h = int(var_h)
for i in list_a:
    i = int(i)
    if i % var_h == 0:
        list_b.append(i)
var_i = len(list_b)
print(int(var_i))
