Have the computational hygiene, if you like, to only go through accessors, only go through methods that are actually provided to you as you do this.
请大家注意计算卫生,如果你喜欢这么说的话,只通过访问器访问数据,当你访问数据的时候,通过提供给你的方法来访问。
A good, hygienic way of doing this is, not only do I not go in and change things except through a pre-defined method, I shouldn't read it other Cartesian than through a pre-defined method.
做这个的方式是,我不仅仅要通过提前定义好的方法,来改变数值,我还应该通过提前定义好的方法,来读这个值,我应该用。
So the question was, why is this return down at this level, it says, well if I ever execute out of this FOR loop, I get to the end of the FOR loop without hitting that branch that took me through the return, then and only then do I want to actually say, gee, I got to this place, there isn't any value to return, none I'm going to return none and none.
问题是,为什么它是在这个级别上返回值呢,意思就是如果我出了这个for循环,就意味着我运行的过程中没有走到任何,带return的支路上去,这时也只有这时我才能说天呐,我终于走到这儿了,这时不会返回任何值,只会返回none和。
