创建新类:通过定义一个类,你创建了一个新的对象类型(type of object)。这意味着你可以创建该类的多个实例,每个实例都是类的一个具体化,拥有类定义的属性(attributes)和方法(methods)。 实例化:创建类的实例的过程称为实例化(instances)。每个实例都拥有自己的属性值,但共享类定义的方法。 类实例(Instance): 属...

preexec_fn:只在Unix平台下有效,用于指定一个可执行对象(callable object),它将在子进程运行之前被调用 close_sfs:在windows平台下,如果close_fds被设置为True,则新创建的子进程将不会继承父进程的输入、输出、错误管道。 所以不能将close_fds设置为True同时重定向子进程的标准输入、输出与错误(stdin, stdout, std...

This is a consequence of the fact that Metaclass(...) returns an object which usually has Metaclass as the __class__. 这是Metaclass(...)返回对象的结果,对象通常把Metaclass作为__class__。 管理多个metaclass 相对于相同的class允许有多个baseclass,每一个baseclass可能有不同的metaclass,但是有个转折...
在3.5 版更改: Add __qualname__ and gi_yieldfrom attributes to generators. The __name__ attribute of generators is now set from the function name, instead of the code name, and it can now be modified. 在3.7 版更改: Add cr_origin attribute to coroutines. inspect.getmembers(object[, pre...
Object-oriented languages design software around objects, which can be real-world entities, such as cars, or abstract concepts, such as numbers. Objects are instances of a class (for example, the class “cars”) and have methods and attributes. This contrasts with languages that center on a ...
