I would like to set the title of a thread (the title seen in ps or top)in Python in order to make it visible to process tracer programs. All the threads of a process are always called python or called file name when /usr/bin/python is used and the script is called via ./script.

Now, I want to change each thread's name. I have a simple script with 4 threads (incl main thread). I use threading to start the threads.

Is there a way that I could achieve this without having to install third-party stuff? Any guidance is appreciated.

Try this: 

def your_function(arg1, arg2, argn):
    * do stuff *


new_thread = threading.Thread(target=your_function, args=(arg1, arg2, argn))
new_thread.name = 'your name'
new.thread.start()

Where new_thread.name is your answer.

Just do the following: t = threading.Thread(name='my_thread')

    Nope, that didn't work, check the link in the comments, pactl must be used in order to register the name to linux process list. – mozcelikors Sep 27 '18 at 11:05
