The final version of the function doesn`t display anything when it runs;it only returns a value.The print statements we wrote are useful for debugging,but once you get the function working,you should remove them.Code like that is called scaffolding because it is helpful for building the program but is not part of the final product.
When you start out,you should add only a line or two of code at a time.As you gain more experience,you might find yourself writing and debugging bigger chunks.Either way,incremental development can save you a lot of debugging time.
The key aspects of the process are:
1.Start with a working program and make small incremental changes.At any porint,if there is an error,you should have a good idea where it is.
2.Use temporary variables to hold intermediate values ... (查看原文)
If you were really thinking like a computer scientist, you would have recognized that uses_all was an instance of a previously-solved problem,and you would have written: (查看原文)
对于一个自学程序设计的入门者而言，他需要一本什么样的书呢？我认为标准有以下三个： 第一，介绍足够用的知识。这一点看似简单，但是却不易掌握，像许多人推荐的 A Byte of Python，内容就明显过少了，而处于另一个极端的 Learning Python 篇幅超过一千页，又明显超出入门者...

这本书是我在来来回回的地铁上看完的，很紧凑，很短小，很易读。这本书是很好的Python入门书籍，也是很好的编程与计算思想入门的书籍，而作者的编排也是遵循渐进的，并且偶然提出的问题(如在讲解string与操作符提出的“Can you think of a property that addition has that str...

很适合入门，基本上扫一遍就能够大致了解整个语言的特性。面向对象部分简单涉及。而对于较为复杂的装饰器、高阶函数，没有涉及。如果仅作为提高兴趣来讲，这本书再适合不过了。

蛮不错的书，但是真觉得不太适合初学者，重点在于题部分需要一部分前置知识，不然很容易做不出来

说真的，这书读得很吃力，感觉自己完全不能像计算机一样思考。如果入门还是推荐《Python编程快速上手 》《 Python编程 从入门到实践》《 Python编程快速上手 让繁琐工作自动化》
