from cereggii import AtomicDict, ThreadSet

counter = AtomicDict({"red": 42, "green": 3, "blue": 14})

@ThreadSet.repeat(10)  # create 10 threads
def workers():
    counter.reduce_count(["red"] * 60 + ["green"] * 7 + ["blue"] * 30)

workers.start_and_join()

assert counter["red"] == 642
assert counter["green"] == 73
assert counter["blue"] == 314
