Python 练习实例85
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
