python - Python中变量和函数名称的命名约定是什么？(What is the naming convention in Python for variable and function names?)

Question

Coming from a C# background the naming convention for variables and method names are usually either camelCase or PascalCase:

(来自C＃背景，变量和方法名称的命名约定通常是camelCase或PascalCase：)

    // C# example
    string thisIsMyVariable = "a"
    public void ThisIsMyMethod()

In Python, I have seen the above but I have also seen underscores being used:

(在Python中，我已经看到了上面的内容，但我也看到了使用下划线：)

    # python example
    this_is_my_variable = 'a'
    def this_is_my_function():

Is there a more preferable, definitive coding style for Python?

(Python有更优选的，明确的编码风格吗？)

Answer 1

See Python PEP 8 .

(请参阅Python PEP 8 。)

Function names should be lowercase, with words separated by underscores as necessary to improve readability.

(函数名称应为小写，并根据需要用下划线分隔，以提高可读性。)

mixedCase is allowed only in contexts where that's already the prevailing style

(只有在已经成为流行风格的情境中才允许使用mixedCase)

Variables...

(变量...)

Use the function naming rules: lowercase with words separated by underscores as necessary to improve readability.

(使用函数命名规则：小写，必要时用下划线分隔，以提高可读性。)

Personally, I deviate from this because I also prefer mixedCase over lower_case for my own projects.

(就个人而言，我与此不同，因为我也喜欢mixedCase在lower_case为我自己的项目。)
