Python: 练习作品-双色球随机组

代码说明

  • 虽然头文件设定了utf-8,但没有中文,因为嫌麻烦。
    这段代码是今天上班公交路上写的,回家路上完工,睡觉前测试修补完成。
  • 代码编写工具,在手机上使用Qpython加完成编写和调试。
  • 这段代码的目标是为了练习class语句的用法。
    虽然学习了一些代码规范,比如逗号空格,运算和逻辑符空格,对齐规范,但是用print时,对print()用法很不习惯,也没有及时查资料,一会儿print(),一会儿print "",需要下次改进。

双色球随机数的对象用法:

  • 创建对象 a = DoubleNumber()
    默认初始化class属性的self.NumList为1~36的数组
    也可以传参 a = DoubleNumber(30)建立一个1~30的数组。
  • 随机抽取数字的方法 Out(),默认为从self.NumList数组里随机抽取7个数,并返回该数组结果。Out(10)为返回随机10个数的数组结果。
  • 打印多组双色球的随机组合 Outs(),默认打印10组双色球随机组合。Outs(100)为100组。
  • 直接执行py文件效果,为输入一个数量,输出该数量的双色球随机组合。
  • import我没试过,结果未知。

如何运行它?保存为py文件后,

  • Windows – 电脑安装有python2.7,打开idle并执行py文件

  • Android – 请安装Qpython后运行py文件即可

  • Linux/Mac – 大部分自带python,如果版本正好是2.7,直接在终端运行py文件
