如何设置它以便线程通信他们完成任务？

Question

从概念上讲，我想完成以下操作，但在理解如何在Python中正确编码时遇到了麻烦：

from threading import Thread
for i in range(0,3):
    t = Thread(target=myfunction)
    t.start()

# wait until threads have finished executing
print 'complete!'

Answer 1

将线程添加到列表中并join()。

from threading import Thread
tlist = []
for i in range(3):
    t = Thread(target=some_function)
    t.start()
    tlist.append(t)

# wait until threads have finished executing
for t in tlist:
    t.join()

print 'complete!'

Answer 2

我从未使用过python，但我认为你所寻找的概念是“信号量”。
