无法将线程附加到数组

Question

So I want to save my threads in an array, like this:

threads = []

To add threads to this array, I create them and append them:

t = thread.start_new_thread(process_client, (client, address))
threads.append(t)

The problem happens when I try to join them:

for thread in threads:
    thread.join

The following error appears:

'int' object has no attribute 'join'

I know the problem here is that when I create the thread the variable t will get an integer that will be appended to the array, setting its type to integer. And when I try to apply the method join() in an integer I get an error. Do any of you guys have a solution to this casting problem?

I'm on python 2.7 btw

Answer 1

thread.start_new_thread returns the thread identifier, not the tread itself. So you are actually appending the tread identifiers which are integers.

You could create and start a Thread object (for that you need to import Thread from threading) then you would have a reference to it

Ex:

t = Thread(target=your_target, args=your_args)
t.start()
threads.append(t)
