What is the smallest number that can be formed by using all odd numbers less than 10 once?
0 10 [OP_LIST_ODD] [OP_LIST_LEN] [OP_LIST_GET_PERM] 1 [OP_LIST_MIN]
var_a = 0
var_b = 10
list_a = []
if var_a%2==0:
    for i in range(var_a+1, var_b+1, 2):
        list_a.append(i)
else:
    for i in range(var_a, var_b+1, 2):
        list_a.append(i)
var_c = len(list_a)
list_b = [str(i) for i in list_a]
list_b = list(itertools.permutations(list_b, var_c))
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_d = 1
list_c=list_b.copy()
list_c.sort()
var_e = list_c[var_d-1]
print(int(var_e))
