Source Code:

#!/usr/bin/python
# -*- coding: UTF-8 -*-

x = int(raw_input("请输入一个数:\n"))
a = x / 10000
b = x % 10000 / 1000
c = x % 1000 / 100
d = x % 100 / 10
e = x % 10

if a != 0:
    print "5 位数:",e,d,c,b,a
elif b != 0:
    print "4 位数:",e,d,c,b,
elif c != 0:
    print "3 位数:",e,d,c
elif d != 0:
    print "2 位数:",e,d
else:
    print "1 位数:",e 

The above example output is:

请输入一个数:
23459
5 位数: 9 5 4 3 2
请输入一个数:
3472
4 位数: 2 7 4 3
