HomeBackend DevelopmentPython Tutorial学习python 之编写简单乘法运算题

实现代码:

#! /usr/bin/python        //处理程序
#filename jiafa.py        //文件名
import sys
 import random
 running = True         //定义running
 while running:         
   a=random.randint(0,15)     //定义a的值为0-15的随机数
  b=random.randint(0,10)     //定义b的值为0-10的随机数
  print a,'*',b       //输出题目
  he=a*b         
   gauess = int(raw_input('Please answer: ')) //定义用户输入值
  if gauess==he:     //判断用户输入输与实际值是否相等

    print "right! Continue? Y/N" // 如果相等,输出正确,并询问是否继续
    fd = raw_input("please Enter: ") //获取键盘输入的值
    str1 = 'Y'
     zhi=cmp(fd,str1) 
     if zhi == 0: //判断键盘输入的值是否是Y,如果是就执行退出,如果不是,就重新回到while,并输出新题
      print "this is over"
       sys.exit() 
   elif gauess<he: //如果输入小于实际值,则提示小了
    print "xiao le "
   else:
     print "da le"//如果输入小于实际值,则提示小了

如果测试,请大家注意格式

The basic syntax for Python list slicing is list[start:stop:step]. 1.start is the first element index included, 2.stop is the first element index excluded, and 3.step determines the step size between elements. Slices are not only used to extract data, but also to modify and invert lists.
