Python threading on close callback [duplicate]

Question

I have Thread and I want to do change some flags when it finish. For example:

import threading 

def on_done():
    # do some printing or change some flags

def worker():
    # do some calculations

t = threading.Thread(target=worker, on_close=on_done)
t.start()

But i was unable to find method like that. Any ideas how could I manage it somehow? The worker function is in separet file, so it does not know abou the flags.

Thaks in advance

Answer 1

One option is to simply wrap the worker function:

def wrapped_worker():
    worker()
    on_done()

Then, set the target to wrapped_worker:

t = threading.Thread(target=wrapped_worker, on_close=on_done)

See this answer for a more in-depth example.
