python 多线程问题？

我有一文件列表，我要开多个线程，比如10个，依次下载列表中的文件，python怎么写？多谢！

简单の来, 用concurrent模块

from concurrent.futures import *

def download(url):
    #bala bala
    return url

with ThreadPoolExecutor(max_workers=10) as executor:
    res = executor.map(download, [1, 2, 3, 4])
    for r in res:
        #bala bala

python中的并发处理的话推荐用gevent代替多线程。

from gevent import monkey
monkey.patch_all()
from gevent.pool import Pool


def download(url):
    # download form url


def main():
    # your files list
    files = [...]

    # 10 current with gevent Pool
    pool = Pool(10)
    pool.map(download, files)

download函数可以使用requests模块来实现下载功能。希望可以帮到你。
