经验丰富的程序员倡导尽可能避繁就简。
Python社区的理念都包含在Tim Peters撰写的“Python之禅”中，要了解这些有关编写优秀Python代码的指导原则，只需在解释器中执行命令import this。

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.
Now is better than never.
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!
优美胜过丑陋。
显式胜过隐式。
简单胜过复杂。
复杂胜过难懂。
扁平胜过嵌套。
稀疏胜过密集。
可读性很重要。
没有特殊情况可以特殊到打破规则。
实用胜过纯粹。
错误不应该无声地传递。
除非明确指出应该忽视。
面对模棱两可，拒绝猜测的诱惑。
应该有一种——最好只有一种——明确的解决方案。
尽管这种方式一开始可能并不明显，除非你是荷兰人。
(Guido van Rossum，荷兰人，Python创始人)
现在做总比不做好。
尽管“从不”做胜过“立刻”做(不思考)。
如果实现很难解释，那就不是一个好主意。
如果实现很容易解释，那么它可能是一个好主意。
命名空间是一个非常棒的主意——让我们多多使用吧!
