Question is in the title.
Code example:
class A:
def start_thread(self):
t1 = threading.Thread(target=something)
t1.start()
a = A()
a.start_thread()
a = A()
So, what happens to the thread, which we started?
What happens to thread started in the class instance when all references to the instance are destroyed (Python)?

The threading module itself keeps a reference to each active Thread object, so a running thread will continue to run even if the reference goes away.
Threads are kept in a separate registry in the Python runtime, and you can "see" them by calling threading.enumerate (https://docs.python.org/3/library/threading.html#threading.enumerate) -
this is no different then not keeping a reference to a thread started in any other way.
