Python 100例题目：判断一个素数能被几个9整除。
程序分析：无。
程序源代码：
#!/usr/bin/python
# -*- coding: UTF-8 -*-
if __name__ == '__main__':
zi = int(raw_input('input a number:\n'))
n1 = 1
c9 = 1
m9 = 9
sum = 9
while n1 != 0:
if sum % zi == 0:
n1 = 0
else:
m9 *= 10
sum += m9
c9 += 1
print '%d can be divided by %d 9' % (sum,c9)以上实例输出结果为：
input a number: 9 9 can be divided by 1 9
