类首先要按照class <类标识符>的形式进行类的定义。 description是类属性,它是这类事物所共同拥有的一个属性。比如对交换机的定义是大家共有的,比如人类的眼睛数量是2个,这也是共有的类属性。 __init__是构造方法,类中的函数称为方法(method)。我们通过对创建对象的时候需要按照这个构造方法的参数来传参赋值,详...

main_thread():返回主线程(thread)对象,一般是python解释器开始时创建的线程。 一、简介 线程对象: 官方解释: TheThreadclass represents an activity that is run in a separate thread of control. There are two ways to specify the activity: by passing a callable object to the constructor, or by overri...

Callingsys.exit()or raising theSystemExitexception is equivalent to calling_thread.exit(). Not all built-in functions that may block waiting for I/O allow other threads to run. (The most popular ones (time.sleep(),file.read(),select.select()) work as expected.) ...
