This example is to test if a number is divisible in Python. It uses some simple code to judge the input odd number which can be divided by 9.
#! /usr/bin/env python3 # -*- coding: utf-8 -*- zi = int(input('Please 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 9s is dividable by %d: %d' % (c9,zi,sum)) r = sum / zi print('%d / %d = %d' % (sum,zi,r))
Please input a number: 13 6 9s is dividable by 13: 999999 999999 / 13 = 76923
Now we can see that 999999 can be divided by 13.
