text = """The Zen of Python, by Tim Peters
Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren't special enough to break the rules.
Although practicality beats purity.
Errors should never pass silently.
Unless explicitly silenced.
In the face of ambiguity, refuse the temptation to guess.
There should be one-- and preferably only one --obvious way to do it.
Although that way may not be obvious at first unless you're Dutch.
Although never is often better than *right* now.
If the implementation is hard to explain, it's a bad idea.
If the implementation is easy to explain, it may be a good idea.
Namespaces are one honking great idea -- let's do more of those!"""

实验总结

               关于这次的实验，我对python中的各种代码又加深了一遍印象，其中对字符串，列表的区别有了更深刻的理解。

               本次实验让我对于平时不习惯使用的函数如sorted title split的用法更加熟悉，对于字符串中的替换操作加深了印象

　　　　 关于这次实验我对于for in 指令的实际作用判断失误，导致代码混乱，耽误了大量时间，需要吸取教训，加强这方面的认识
