我有两个函数从两个不同的连接接收数据，我应该在从其中之一获得结果后关闭这两个连接。

def first():
    gevent.sleep(randint(1, 100))  # i don't know how much time it will work
    return 'foo'

def second():
    gevent.sleep(randint(1, 100))  # i don't know how much time it will work
    return 'bar'

然后我生成每个函数：

lst = [gevent.spawn(first), gevent.spawn(second)]

gevent.joinall阻塞当前的 greenlet，直到两个 greenlet 都lst准备好。

gevent.joinall(lst)  # wait much time
print lst[0].get(block=False)   # -> 'foo'
print lst[1].get(block=False)   # -> 'bar'

我想等到第一个或第二个 greenlet 准备好：

i_want_such_function(lst)  # returns after few seconds
print lst[0].get(block=False)  # -> 'foo' because this greenlet is ready
print …
