如何使用多线程在Python中快速下载1000+ .txt文件

import os
import requests
import threading

def download_file(url, save_path):
    response = requests.get(url)
    with open(save_path, 'wb') as file:
        file.write(response.content)

def multi_thread_download(urls, save_dir):
    threads = []
    for i, url in enumerate(urls):
        file_name = f'file_{i}.txt'
        save_path = os.path.join(save_dir, file_name)
        thread = threading.Thread(target=download_file, args=(url, save_path))
        threads.append(thread)
        thread.start()

    for thread in threads:
        thread.join()

urls = [
    'http://example.com/file1.txt',
    'http://example.com/file2.txt',
    'http://example.com/file3.txt',
    ...
    'http://example.com/file1000.txt'
]

save_directory = '/path/to/save/files'

multi_thread_download(urls, save_directory)
