Get access to existing thread python

Pretend one have a script with creating some testing Thread: test1.py

import threading
import time


class Test(threading.Thread):
    def __init__(self, name, alist):
        threading.Thread.__init__(self)
        self.alist = alist
        self.name = name

    def run(self):
        print "Starting thread " + self.name
        self.append_to_alist(self.alist)
        print "Exiting thread" + self.name

    def append_to_alist(self, alist):
        for x in range(5):
            self.alist.append(alist[-1]+1)
            time.sleep(10)


def main():
    alist = [1]
    # Create new thread
    thread = Test("Test thread", alist)
    thread.start()
    thread.join()
    print alist
main()

Now I run it python test1.py and then I want to run another script test2.py in order to modify existing Test thread which is working, something like this, test2.py:

import threading
thread = somehow_get_access_to_Test_thread()
thread.alist.append('test')

Is it possible?

To my knowledge there is no way for the threads to interact directly. Not only are they different threads, but they also run in separate Python processes.

In this case I believe the simplest solution is to have the list thread listen on a TCP port, and the other thread write to that port.

See for example this library.
