use a lock, and make sure that anyone that needs access to the shared
state you're manipulating in that section uses the same lock.
lock = threading.Lock() # or RLock() etc [1]
with lock:
section
this only works if everyone honors the lock, of course; there's no way
in Python to lock out non-cooperating external threads.

Thats true, but this will ensure mutual exclusion; not atomicity
AFAIC that kind of mutual exclusion is what atomicity is about. What
else do you expect to happen?
