为什么我得到 NameError: name 'as_completed' is not defined（我从 concurrent.futures 导入 ThreadPoolExecutor）

Question

我有以下代码：

从 concurrent.futures 导入 ThreadPoolExecutor

def load_database():
    with ThreadPoolExecutor(max_workers=10) as executor:
        futures = [executor.submit(load_person, x) for x in range(max_people - 1)]
        for future in as_completed(futures):
            return(future.result()) 
        print(futures)

我收到“NameError: name 'as_completed' 未定义”

我是否需要导入其他东西才能使用 as_completed？

谢谢， 克莉丝

Answer 1

as_completed 住在 concurrent.futures 所以你需要 from concurrent.futures import as_completed
