python实现抖音视频批量下载

本文实例为大家分享了python实现抖音视频批量下载的具体代码，供大家参考，具体内容如下

这里就拿最近很火的抖音视频为例，利用API来实现用户抖音视频的批量下载

主要用到的模块有

1、requests模块；

2、bs4模块；

import requests
import bs4
import os
import json
import re
import sys
import time
from contextlib import closing
requests.packages.urllib3.disable_warnings()

           }

     temp = video_names[num].replace('\\', '')
     video_name = temp.replace('/', '')
