自己改了一下要下载的url，一个网页，一个exe，一个PDF
import requests
import multiprocessing
def download_file(url):
local_filename = url.split('/')[-1]
with requests.get(url, stream=True) as r:
r.raise_for_status()
with open(local_filename, 'wb') as f:
for chunk in r.iter_content(chunk_size=8192):
if chunk:
f.write(chunk)
return local_filename
if __name__ == '__main__':
urls = ['https://www.cnblogs.com/pu369/p/17221436.html',
'http://www.zs.gov.cn/attachment/0/402/402310/1931387.pdf',

with multiprocessing.Pool(processes=3) as pool:
result = pool.map(download_file, urls)
print(result)
