How many three digit numbers are there that are less than 403 and greater than 285?
285 1 [OP_ADD] 403 1 [OP_SUB] 1 [OP_LIST_ARANGE] [OP_LIST_LEN]
var_a = 285
var_b = 1
var_c = var_a + var_b
var_d = 403
var_e = 1
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 = len(list_a)
print(int(var_h))
