import threading

#类

#Thread()

#构造方法

#threading.Thread()

#__init__(self, group=None, target=None, name=None, args=(), kwargs=None, verbose=None)

#group:保留为将来扩展时，可以类被实现

#target:要执行的方法，也叫被调用的方法

#name：is the thread name.

#args：tuple参数，默认(),tuple

#kwargs：关键字参数dict，默认dict

'''

     |      *group* should be None; reserved for future extension when a ThreadGroup

     |      class is implemented.

     |

     |      *target* is the callable object to be invoked by the run()

     |      method. Defaults to None, meaning nothing is called.

     |

     |      *name* is the thread name. By default, a unique name is constructed of

     |      the form "Thread-N" where N is a small decimal number.

     |

     |      *args* is the argument tuple for the target invocation. Defaults to ().

     |

     |      *kwargs* is a dictionary of keyword arguments for the target

     |      invocation. Defaults to {}.

     |

     |      If a subclass overrides the constructor, it must make sure to invoke

     |      the base class constructor (Thread.__init__()) before doing anything

     |      else to the thread.

#__repr__

#作用：返回一个可用来表示对象的可打印字符串

#1）尝试生成这样一个字符串，将其传给eval()可重新生成同样的对象

#2）一个类class可以通过__repr__成员来控制repr()函数作用在其实例上时的行为

class D():

    def __str__(self):

        return 'a.__str_-'

    def __repr__(self):

        return 'a.__repr__'

>>> dr=D()

>>> dr

#getName(self)：返回线程名

#isAlive(self): 返回线程是否活动的

#isDaemon(self):判断线程是否随主线程一起结束

#join(self, timeout=None):等待线程终止，Wait until the thread terminates.

#run(self)：表示线程活动的方法。

#setDaemon(self, daemonic)#设置子线程是否随主线程一起结束，必须在start()之前调用。默认为False。

#setName(self, name)：设置线程对象名称

#start(self)：启动线程
