类对象(class object) 在解析器执行完类定义后,会生成一个类对象(class object),这个类对象封装了在类定义中的那些属性(attributes)和函数(function),对类对象可进行的操作:读取属性,设置或添加属性和实例化: class MyClass: """A simple example class""" ...
定义类, 使用class关键字, 一般类名称大写开头, 继承类需要在类名称后加上继承类名作为参数例如 class NamedList(list): 3. Class methods (your code) are defined in much the same way as functions, that is, with the def keyword. Class attributes (your data) are just like variables that exist wi...
If the object is a type or class object, the list contains the names of its attributes, and recursively of the attributes of its bases; 如果参数是类型或类对象,则返回的列表中包含其属性的名称,并以递归方式获取其基类的属性的名称; Otherwise, the list contains the object’s attributes’ names, ...
属性(Attributes)指在当前这个object里,还有一些其他的python object。方法(method)指当前这个object自带的一些函数,这些函数可以访问object里的内部数据。 通过obj.attribute_name可以查看: 代码语言:javascript 复制 a='foo'a.<Press Tab> 可以通过getattr函数来访问属性和方法: ...
