Question

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 threading
import thread
import time
def 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 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()

# -*- coding: utf-8 -*-
import threading
import thread
import time


class Test(object):
    def __init__(self):
        # threading.Thread.__init__(self)
        self._sName = "machao"

    def process(self):
        #args是关键字参数，需要加上名字，写成args=(self,)
        th1 = threading.Thread(target=Test.buildList, args=(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()
