When you access the third item, Python knows it is an integer object.
在访问第三个数据项时,Python知道它是一个整数对象。
But it's the third item - "how to use it" - that can only be learned over months of working with a language and that's where the real magic happens.
只有第三项,“如何使用它”-要花上你几个月的时间去跟这门语言打交道,真正的奇迹就在此发生。
Maybe you can use some trick to select the third item in a list, but how do you select an item that might appear in any position in a variable-length list?
或许,你可以用某种小技巧来选择列表中的第三项吧,但是你如何选择一个出现在可变长度的列表中任何位置的表项呢?
