Requests庫，高度封裝的http庫

import requests

url = 'http://down.sandai.net/thunder9/Thunder9.0.18.448.exe'
filename = url.split('/')[-1]  #獲取文件名
r = requests.get(url,stream = True)

with open(filename,'wb') as f:
    p = 0  #下載計(jì)數(shù)器
    chunk_size = 4096 #塊大小
    try:
        while True:
            for data in r.iter_content(chunk_size):
                p += f.write(data)
                
                print('%d' % (p))
        
    except Exception as e:
        print(e)
    finally:
        print('下載完畢！')

urllib庫，操作上能比Requests靈活一點(diǎn)，沒有特殊需求的話基本沒什么差別

import urllib.request

url = 'http://down.sandai.net/thunder9/Thunder9.0.18.448.exe'
resp = urllib.request.urlopen(url)
filename = url.split('/')[-1]
with open(filename,'wb') as f:
    p = 0 #下載計(jì)數(shù)
    buffsize = 4096 #塊大小
    try:
        while True:
            buff = resp.read(buffsize)
            if not buff:    #buff為空，即下載完畢，結(jié)束循環(huán)
                break
            p += f.write(buff)
            print('%d' % p)
    except Exception as e:
        print(e)
    finally:
        print('下載完畢！')

還有個(gè)一句話的 

import urllib
urllib.urlretrieve(url, ‘test.jpg’)
