1.生成随机数
          import random    #这个是注释，引入模块
          rnd = random.randint(1,500)#生成1-500之间的随机数

2.读文件

         f = open("c:\\1.txt","r")
         lines = f.readlines()#读取全部内容

//JavaScript callee 用法示例

function factorial(num) {
    if (num <= 1) {
		return 1;
	} else {
		return num * arguments.callee(num - 1);
	}
}
