  • python开发_python代码风格(coding style)

    我们要做python开发,我想python中的代码风格我们有必要了解一下

    这样对我们自己和他们所编写的代码都有好处的。

    下面是8点重要代码风格注意事项:

    ONE :  Use 4-space indentation, and no tabs.--用4个空格键进行代码缩进,不要使用tab键.

    4 spaces are a good compromise between small indentation (allows greater nesting depth) and large indentation (easier to read). Tabs introduce confusion, and are best left out.
    TWO :  Wrap lines so that they don’t exceed 79 characters.-- 每一行代码不要超过79字符.

    This helps users with small displays and makes it possible to have several code files side-by-side on larger displays.
    THREE :  Use blank lines to separate functions and classes, and larger blocks of code inside functions. -- 在函数或者类中使用空白行
    FOUR :  When possible, put comments on a line of their own.--添加注释,这个可以帮助你自己和他人阅读代码
    FIVE :  Use spaces around operators and after commas, but not directly inside bracketing constructs: a = f(1, 2) + g(3, 4).--在编写代码的过程中,注意使用空格,这样使得你的代码看上去清晰,美观
    SIX :  Name your classes and functions consistently; the convention is to use CamelCase for classes and lower_case_with_underscores for functions and methods. Always use self as the name for the first method argument --使用驼峰命名法命名类名;使用'lower_case_with_underscores '这样的方式命名方法或者函数
    SEVEN :  Don’t use fancy encodings if your code is meant to be used in international environments. Python’s default, UTF-8, or even plain ASCII work best in any case. -- 统一使用UTF-8的编码方式进行编码
    EIGHT :  Likewise, don’t use non-ASCII characters in identifiers if there is only the slightest chance people speaking a different language will read or maintain the code.--不要使用非ascii字符标识符
