python多线程，获取多线程的返回值

代码如下：

# coding=utf-8

import threading
from time import ctime, sleep

# 多线程如何返回值
class MyThread(threading.Thread):

def __init__(self,func,args=()):
super(MyThread,self).__init__()
self.func = func
self.args = args

def run(self):
self.result = self.func(*self.args)

def get_result(self):
try:
return self.result # 如果子线程不使用join方法，此处可能会报没有self.result的错误
except Exception:
return None

# 多线程
def music(func):
for i in range(2):
print ("I was listening to %s. %s" %(func,ctime()))
sleep(1)

def move(func):
for i in range(2):
print ("I was at the %s! %s" %(func,ctime()))
sleep(5)

def add(a, b):
#print ('a+b:', a+b)
return a+b

threads = []
t1 = threading.Thread(target=music, args=(u'爱情买卖',))
threads.append(t1)
t2 = threading.Thread(target=move, args=(u'阿凡达',))
threads.append(t2)

t3 = MyThread(add, args=(1,2,))
threads.append(t3)

if __name__ == '__main__':
for t in threads[:2]:
t.setDaemon(True)
t.start()

for t in threads[2:]:
t.setDaemon(True)
t.start()
print ("MyThread:a+b=%d ! %s" % (t.get_result(),ctime()))

print ("all over %s" %ctime())

输出结果：
