python 按照长度对字符串进行分隔，不够的补0

比如将字符串安装8个一组进行分隔并打印出来

#!/usr/bin/python
#-*- coding:utf-8 -*-
in_str = raw_input()
if len(in_str) % 8 == 0:
	time = len(in_str) // 8
	for i in range(time):
		print in_str[i*8:i*8+8]
else:
	time = len(in_str) // 8
	for i in range(time):
                print in_str[i*8:i*8+8]
	print  in_str[time*8:]+"0"*(8-(len(in_str) % 8))
