python中如何对类的成员函数开启线程?

python中如何对类的成员函数开启线程?

单独对某个函数开启线程是可以的,比如下面的代码:import threadingimport threadimport timedef doWaiting():print 'start waiting:', time.strftime('%H:%M:%S')time.sleep(3)print 'stop waiting', time.strftime('%H:%M:%S')thread1 = threading.Thread(target = doWaiting)thread1.start()time.sleep(1) #确保线程thread1已经启动print 'start join'thread1.join() #将一直堵塞,直到thread1运行结束。print 'end join'但是对类的成员函数开启线程,程序报错:th1 = threading.Thread(target = Test.buildList , (self ,)) SyntaxError: non-keyword arg after keyword arg程序如下:import threadingimport threadimport timeclass Test(object):def __init__(self):#threading.Thread.__init__(self)self._sName = "machao"def process(self):th1 = threading.Thread(target = Test.buildList , (self ,)) th1.start()th1.join()def buildList(self):while True:print "start"time.sleep(3)test = Test()test.process()

程序如下:
import threading
import thread
import time
class Test(object):
def __init__(self):
#threading.Thread.__init__(self)
self._sName = "machao"

def process(self):
th1 = threading.Thread(target = Test.buildList , (self ,))
th1.start()
th1.join()

def buildList(self):
while True:
print "start"
time.sleep(3)

test = Test()
test.process()
