python-3.x - 如何在 Python 中为 ThreadPoolExecutor 线程赋予不同的名称

Question

我有以下用于创建线程和运行它们的代码。

from concurrent.futures import ThreadPoolExecutor
import threading


def task(n):
    result = 0
    i = 0
    for i in range(n):
        result = result + i
    print("I: {}".format(result))
    print(f'Thread : {threading.current_thread()} executed with variable {n}')

def main():
    executor = ThreadPoolExecutor(max_workers=3)
    task1 = executor.submit(task, (10))
    task2 = executor.submit(task, (100))

if __name__ == '__main__':
    main()

当我在 Windows 10 机器上运行代码时，这是生成的输出:

I: 45
Thread : <Thread(ThreadPoolExecutor-0_0, started daemon 11956)> executed with variable 10
I: 4950
Thread : <Thread(ThreadPoolExecutor-0_0, started daemon 11956)> executed with variable 100

Process finished with exit code 0

正如我们所见，这两个线程具有相同的名称。我如何通过给它们不同的名称来区分它们？这是否是 concurrent.futures 类的一个特性？

非常感谢您的回答。

来自 docs :

New in version 3.6: The thread_name_prefix argument was added to allow users to control the threading.Thread names for worker threads created by the pool for easier debugging.

使用 thread_name_prefix 参数:

concurrent.futures.ThreadPoolExecutor(max_workers=None, thread_name_prefix='')
