python用正则获取天气数据

需要用正则的方式提取中国天气网站上重庆地区所有区县当天的最高温度和最低温度

这是出错的代码

import requests
from bs4 import BeautifulSoup
from pyecharts.charts import Bar
from pyecharts import options as opts
ALL_DATA=[]
def parae_page(url):
    header={'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 /'
            'KHTML, like Gecko) Chrome/85.0.4183.102 Safari/537.36'}
    response=requests.get(url,headers=header)

    text=response.content.decode('utf-8')
    soup=BeautifulSoup(text,'lxml')

    conMidtab=soup.find('div',class_='conMidtab')

    tables=conMidtab.find_all('table')


    table=tables[1]
    trs=table.find_all('tr')[2:]

    for index, tr in enumerate(trs):
        tds = tr.find_all('td')

        if index == 0:
            city_td = tds[1]
            temp_max_td = tds[4]
        else:
            city_td = tds[0]
            temp_max_td = tds[3]
        city=list(city_td.stripped_strings)[0]
        max_temp=list(temp_max_td.stripped_strings)[0]
        temp_td=tds[2]
        min_temp=list(temp_td.stripped_string)[0]

        ALL_DATA.append({'city':city,'max_temp':max_temp,'min_temp':int(min_temp)})
        print({'city':city,'max_temp':max_temp,'min_temp':int(min_temp)})

def main():
    urls={'http://www.weather.com.cn/textFC/xn.shtml'}
    for url in urls:
        parae_page(url)

if __name__=='__main__':
    main()

这代码运行后提示的错误

诶，有点不知道main哪里出问题了

可以帮忙看看吗
