一、thread（不推荐）
1 import thread 2 def foo(a): 3 print a 4 5 thread.start_new_thread(foo,(a))
二、threading
1 import threading 2 class MyThread(threading.Thread): 3 # def __init__(self,a): 4 # threading.Thread.__init__(self[,name=xxx]) 5 # self.a=a 6 def run(self): 7 pass 8 thr=MyThread() 9 thr.start()
三、
1、Lock，RLock
1 #主线程 2 mutex = threading.Lock() 3 #子线程 4 mutex.acquire([timeout]) 5 mutex.release()
2、Condition
#主线程 con = threading.Condition() #子线程 con.acquire() con.notify() con.wait() #... con.release()
3、Queue
import Queue #主线程 q=Queue.Queue() #FIFO,Maxsize #子线程 q.put(msg)#(item,block=True,timeout=None) q.get(msg) #q.qsize()==0
4、threading.Event
5、thr.join([timeout]) 等待子线程执行结束
6、thr.setDaemon(bool) 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。
7、getName(),setName(),isDaemon(),isAlive()
8、activeCount(),enumerate()
四、
#coding=utf8 import threading class MyTread(threading.Thread): def run(self): while True: mylock.acquire() if len(task)==0: mylock.release() break t=task[0];del task[0] mylock.release() pass def main(): global task,mylock task=range(100) mylock=threading.Lock() for i in range(5): t=MyThread() # lt.append(t) t.start() for t in [li for li in threading.enumerate() if li.name!='MainThread']: #lt t.join() print threading.activeCount(),[li.name for li in threading.enumerate()] if __name__ == '__main__': main()
