How many two-digit numbers can be formed by taking two odd numbers greater than 1 and less than 9 and using them once?
1 1 [OP_ADD] 9 1 [OP_SUB] [OP_LIST_ODD] 2 [OP_LIST_GET_PERM] [OP_LIST_LEN]
var_a = 1
var_b = 1
var_c = var_a + var_b
var_d = 9
var_e = 1
var_f = var_d - var_e
list_a = []
if var_c%2==0:
    for i in range(var_c+1, var_f+1, 2):
        list_a.append(i)
else:
    for i in range(var_c, var_f+1, 2):
        list_a.append(i)
var_g = 2
list_b = [str(i) for i in list_a]
list_b = list(itertools.permutations(list_b, var_g))
list_b = [''.join(num_list) for num_list in list_b]
list_b = [str_num for str_num in list_b if str_num[0] != '0']
list_b = [float(i) for i in list_b]
var_h = len(list_b)
print(int(var_h))
