For example: (recommended learning:Python video tutorial)

#!/usr/bin/python<br># -*- coding: UTF-8 -*-<br>x = 7<br>i = 1<br>flag = 0<br><br>while i <= 100:<br>    if (x%2 == 1) and (x%3 == 2) and (x%5 == 4) and (x%6==5):<br>        flag = 1<br>    else:<br>        x = 7 * (i+1) # 根据题意，x一定是7的整数倍，所以每次乘以7<br>    i += 1<br><br>if flag == 1:<br>    print('阶梯数是：', x)<br>else:<br>    print('在程序限定的范围内找不到答案！')<br>

Output result:

阶梯数是： 119<br>

flag is used as the judgment condition of if, The original value is 0, When the if statement in while is satisfied, flag=1, that is, x is found that satisfies the condition of the if statement, and then the loop is jumped out.
