python爬取糗事百科，该如何正确保存到本地文件夹?报错

我的程序已经可以爬取网络内容,但不太清楚怎么保存到当地文件夹,用网上方法试着做,但是有报错

import urllib
import urllib.request
import requests ##导入requests
from bs4 import BeautifulSoup ##导入bs4中的BeautifulSoup
import os


for i in range(35):
    page=i
    headers = {'User-Agent':"Mozilla/5.0 (Windows NT 6.1; WOW64)"}
    all_url = 'http://www.qiushibaike.com/hot/page/'+str(page)  ##开始的URL地址
    start_html = requests.get(all_url,headers=headers)
    Soup = BeautifulSoup(start_html.text, 'lxml')
    all_a = Soup.find('div', class_='col1').find_all(class_='content')
    for j in all_a:
        title = j.get_text() #取出a标签的文本
        path = str(title).strip()
        
        os.makedirs(os.path.join("C:\\Users\\DOU XIAOFEI\\Desktop\\wintercode\\funstory", path))
        os.chdir("C:\\Users\\DOU XIAOFEI\\Desktop\\wintercode\\funstory\\"+path) ##切换到上面创建的文件夹
        name = all_url[-9:-4]
        allurl = request.get(all_url,headers=headers)
        f = open(name + '.html', 'ab')
        f.write(allurl.content)
        f.close()
