    Nice work! I will send you the prize money.

    Question:

    You create a separate dict for each thread:
    results.append({})

    And you also lock this dict for every write:

          lock.acquire()
            if operation not in self.stats:
                self.stats[operation] = 1
            else:
                self.stats[operation] += 1
            lock.release()

    Is this required since the dict is still part of the results list? I do not know, so this is a genuine question.

    My solution is a bit different in that regard and also yields faster times, I will be submitting a tutorial soon.

    Yeah, I don't think that lock is necessary. I used it because I thought since they are all part of a larger array I should use it to be safe, but I think it would be just as safe without. Nice catch!
