What do you get when adding all natural numbers that are less than or equal to 31 and greater than 28?
28 1 [OP_ADD] 31 1 [OP_LIST_ARANGE] [OP_LIST_SUM]
var_a = 28
var_b = 1
var_c = var_a + var_b
var_d = 31
var_e = 1
list_a = [i for i in range(var_c, var_d + 1, var_e)]
list_a = [float(i) for i in list_a]
var_f = sum(list_a)
print(int(var_f))
