在Python中用到的格式有三种:lower_underscore、UPPER_UNDERSCORE、CamelCase,不会用到mixedCase。 lower_underscore:小写字母跟下划线(除了常量和类名,剩下的所有名字都是小写下划线,包括:module模块、variable变量、function函数、method方法,他们在Python中通常被看做是一个变量被使用、被传递,所以他们的命名方式是一致的...
命名约定 Prescriptive: Naming Conventions 中指明:package, module, function, method命名采用lower_case_with_underscores风格,其中包名尽量不要用下划线(因此package和module最好只有一个单词),class采用CapWords风格,内部类和非public方法以下划线开头;常量采用ALL_CAPITAL_WITH_UNDERSCORES风格; 参考: lower_case_with_un...
A docstring is a string literal that occurs as the first statement in a module, function, class, or method definition. Typically, you use a documentation string to automatically generate the code documentation. As such, a docstring can be accessed at run-time using the obj.__doc__ special ...
This latter terminology, dunder, refers to a particular naming convention that Python uses to name its special methods and attributes. The convention is to use double leading and trailing underscores in the name at hand, so it looks like .__method__().Note: In this tutorial, you’ll find...
Method Names and Instance Variables Use the function naming rules: lowercase with words separated by underscores as necessary to improve readability. Use one leading underscore only for non-public methods and instance variables. To avoid name clashes with subclasses, use two leading underscores to invo...
Spaces are the preferred indentation method. Tabs should be used solely to remain consistent with code that is already indented with tabs. Python 3 disallows mixing the use of tabs and spaces for indentation. Python 2 code indented with a mixture of tabs and spaces should be converted to using...
和变量解析不同,Python 会按照特定的顺序遍历继承树,就是方法解析顺序(Method Resolution Order,MRO)。类都有一个名为mro 的属性,值是一个元组,按照方法解析顺序列出各个超类,从当前类一直向上,直到 object 类。 Python 中有一种特殊的类是元类(metaclass)。元类是由“type”衍生而出,所以父类需要传入type,元类...
First, you use the .append() method to add new fruits as strings to the end of fruits, and then you add new rows to the end of rows.Remove ads Using Complementary Ways to Create VariablesIn Python, you’ll find a few alternative ways to create new variables. Sometimes, defining ...
