Re: [Python-ideas] Atomic counter / atomic increment

import threading

class AtomicCounter: def __init__(self, initial=0): self.value = initial self._lock = threading.Lock()

def increment(self, num=1): with self._lock: self.value += num return self.value

Some late nitpicking, sorry: This is not an atomic counter, it's a thread-safe counter. And since being thread-safe is rarely a bad idea, especially assuming someone will manage to Kill GIL, I would just call it a "counter" or Counter. (Of course, atomic/lock-free implementations are nice when possible.) -- Koos
