上述代码通过调用executor.submit()函数,把aggregate_news()函数放入到future的队列to_do_list中。然后通过调用as_completed(to_do_list)函数把执行完后的future的结果输出出来。 好了到处python的future讲解结束,如果你还有疑问欢迎大家留言。发布于 2021-06-12 22:25 ...

不管是asyncio还是concurrent.futures.Future都会有几个函数是返回future,其他函数则是使用future,在最开始的例子中我们使用的Executor.map就是在使用future,返回值是一个迭代器,迭代器的__next__方法调用各个future的result方法,因此我们得到的是各个futrue的结果,而不是future本身 关于future.as_completed函数的使用,这里...

Thepython-futureproject was created in 2013 to attempt to save Python from the schism of version incompatibility that was threatening to tear apart the language (as Perl 6 contributed to the death of Perl). That time is now past. Thanks to a huge porting effort across the Python community,...
尽管future模块提供了done方法用于判断任务是否执行完成,但是不能在主线程中一针对某个任务都写一个判断语句。最好是当某个任务结束了,它自动给主线程返回一个结果,而不是一直判断每个任务是否结束,此时as_completed方法就派上用场了。as_completed有两个参数,fs是future对象构成的序列,timeout是等待的最小秒数。而...
