I made a simple ThreadManager class that receives tasks and spawns threads to complete the tasks. Currently it keeps all the threads alive until I explicitly set threadmgr.waiting=False and all of the tasks are complete. I'm trying to eliminate the need for the former. What I would prefer is that when the frame that instantiates the threadmgr terminates it automatically tells the threadmgr to stop waiting for new tasks. I've been looking at the inspect module and am able to get a line number that the parent frame is on but I don't see an easy way to determine if that frame has completed... It's probably a fairly simple solution. Thanks in advance.

The normal solution is to use a 'with' statement

from contextlib import contextmanager

def threadmgr_running(*args, **kwd):
    threadmgr = ThreadManager(*args, **kwd)
    threadmgr.start() # or whatever
        yield threadmgr
        threadmgr.waiting = False

# in code

with threadmgr_running(...) as threadmgr:
    etc # the threadmgr terminates automatically after this block
for the props you deserve but didn't get

thanks, that gave me the idea to just add __enter__ and __exit__ methods to the class and use it within a with statment.
