python2.4前有个thread模块支持多线程编程,2.4后新增了threading模块,提供更高级别和更强大的线程支持.
- threading.activeCount():返回激活的线程对象的数量
- threading.currentThread():返回当前cpu执行的线程对象
- threading.enumerate(): 返回当前激活的线程对象列表
除此之外,threading提供了很多和java中Thread类一样的方法:(注意这是都是实例方法)
- run(): The run() method is the entry point for a thread.
- start(): The start() method starts a thread by calling the run method.
- join([time]): The join() waits for threads to terminate.
- isAlive(): The isAlive() method checks whether a thread is still executing.
- getName(): The getName() method returns the name of a thread.
- setName(): The setName() method sets the name of a thread.
创建线程的方式有两种:1)继承threading.Threada.创建一个threading.Thread的子类
b.覆盖
init(self [,args])
c.重写run方法
#!/usr/bin/python #!coding=utf-8import threadingimport timeexitFlag = 0class MyThread(threading.Thread):def __init__(self, threadID, name, counter):threading.Thread.__init__(self)self.threadID = threadIDself.name = nameself.counter = counterdef run(self):task()def task(self): """线程要执行的任务""" print "starting " + self.name print "exiting " + self.name #创建线程thread1 = MyThread(1,"Thread-1", 1)thread2 = MyThread(2,"Thread-2", 2)#启动线程thread1.start()thread2.start()#等待线程结束thread1.join()thread2.join()print "exiting main thread"2)任务函数作为参数传递到Thread方法中
