想不出来有啥其他算法简化了，就用最傻逼的elif好了

import requests,re

def del_join(del_content,list_content):
    for i in list_content:
        list=re.split(del_content,i)
        str=""
        print("{}\t".format(str.join(list)),end="")

url="https://www.tianqi.com/chongqing/7/"
headers={
"user-agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/106.0.0.0 Safari/537.36 Edg/106.0.1370.52"
}
html=requests.get(url,headers=headers).text

temp_ch=re.compile(r'<div class="weaul_z"><span>(.*?)</div>')
date_ch=re.compile(r'<span class="fl">(.*?)</span>')
week_ch=re.compile(r'<span class="fr">(.*?)</span>')

temp=temp_ch.findall(html)
date=date_ch.findall(html)
week=week_ch.findall(html)

for i in date:
    print("{}\t".format(i),end="")
print("\n")
for i in week:
    print("{}\t".format(i),end="")
print("\n")
del_join("<span>|</span>",temp)

用requests和re模块，本来想用beautifulsoup，但爬出来会有乱码，放弃了

re具体的筛选就用温度、日期前边的div类型，然后出来的是个list

只有温度中间有其他的字符，就定义一个”del_join”函数，把温度中间的span和/span删掉再拼接起来就好了

搭建novelai，显卡1066，搭了也没啥用，懒得搭了
