global count python
Two separate processes don't share the same globals hence the result you get. I think this should help finding a way to share variables ..., Use a mutex: import threading iid = 1 iid_lock = threading.Lock() def next_id(): global iid with iid_lock: result = iid iid += 1 return result.
