用def可以定义一个方法，方法必须以一个小写字母开头 ** 如果使用大写字母，不会出错，但是Ruby会优先猜测这是一个常量而不是一个方法调用，解析可能出错 指定形参默认值 def cool_dude(

所有的数字也是对象。可以对各种形式的消息做出响应. 整数也支持几种有用的迭代器。 3.times { print X } 1.upto(5) { |i| print i, } 9.downto(7)

a[3.14159, pie ,49] a.class - Array a.length - 3 a[3] - nil []实际上是一个方法。 如果用负数作为索引，那么会从数组末端开始计数 数组可以嵌
