A number is said to be not less than 30 and not more than 50. Find the sum of all the possible values of the number.
30 50 1 [OP_LIST_ARANGE] [OP_LIST_SUM]
var_a = 30
var_b = 50
var_c = 1
list_a = [i for i in range(var_a, var_b + 1, var_c)]
list_a = [float(i) for i in list_a]
var_d = sum(list_a)
print(int(var_d))
