测试 Python 任务或未来是否成功完成的最干净的方法是什么？

Question

What is the cleanest way to test that a python Task or Future has completed successfully (neither canceled nor failed)? This is the best I have come up with:

success = future.done() and not future.cancelled() and future.exception() is None

and it seems clumsy and error-prone, because it is easy to forget the not future.cancelled() .

Answer 1

It is looking good for me. You can wrap in a function if you prefer:

def is_success(future):
   return future.done() and not future.cancelled() and future.exception() is None
