The idioms of a programming language are defined by its users. Over the years, the Python community has come to use the adjective Pythonic to describe code that follows a particular style. The Pythonic style isn’t regimented or enforced by the compiler. It has emerged over time through experience using the language and working with others. Python programmers prefer to be explicit, to choose simple over complex, and to maximize readability. (Type import this into your interpreter to read The Zen of Python.)
编程语言的习惯用法是由用户定义的。多年来，Python社区已经开始使用形容词Pythonic来描述遵循某种特定风格的代码。Pythonic风格不受编译器的约束或强制，它是通过长期的使用语言和与他人合作的经验中逐渐出现的编程范式。Python程序员更喜欢显示的、简洁而不是复杂的、高可读性的代码风格。（在您的解释器里输入 import this 阅读Python之禅。）
Programmers familiar with other languages may try to write Python as if it’s C++, Java, or whatever they know best. New programmers may still be getting comfortable with the vast range of concepts that can be expressed in Python. It’s important for you to know the best—the Pythonic—way to do the most common things in Python. These patterns will affect every program you write.
熟悉其他语言的程序员可能会尝试编写Python，好像它是C++、Java或任何他们最了解的语言。新程序员可能仍然对可以用Python表达大量的概念感到舒服。重要的是，你要知道最好的——在Python中做最常见事情的Pythonic方式。这些模式会影响你编写的每一个程序。
