为什么会报错啊？你们能试一下吗？求大佬指点

import requests
from bs4 import BeautifulSoup
from pyecharts.charts import Bar

all_data = []


def parse_page(url):# 解析url页面函数
    headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:75.0) Gecko/20100101 Firefox/75.0'}
    response = requests.get(url, headers=headers)
    # print(response.content.decode('utf-8'))#当解码之后的页面有乱码说明用response.test()猜错了解码方式，则应该改成response.content.decode('utf-8')
    text = response.content.decode('utf-8')

      for index, tr in enumerate(trs):
            tds = tr.find_all('td')
            city_td = tds
            if index == 0:
                city_td = tds
            city = list(city_td.stripped_strings)
            temp_td = tds[-2]
            min_temp = list(temp_td.stripped_strings)
            data = all_data.append({'city': city, 'min_temp': int(min_temp)})

def main():
    urls = {'http://www.weather.com.cn/textFC/hb.shtml',

            'http://www.weather.com.cn/textFC/db.shtml',

    all_data.sort(key=lambda data: data['min_temp'])
    data = all_data
    cities = list(map(lambda x: x['city'], data))
    temps = list(map(lambda x: x['min_temp'], data))
    chart = Bar('中国气温最低温度排行')
    chart.add('', cities, temps)
    chart.render('temperature1.html')


if __name__ == '__main__':
    main()




报错是这样的：
Traceback (most recent call last):

    main()

这样试试：

import requests
from bs4 import BeautifulSoup
from pyecharts.charts import Bar

all_data = []


def parse_page(url):# 解析url页面函数
    headers = {'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:75.0) Gecko/20100101 Firefox/75.0'}
    response = requests.get(url, headers=headers)
    # print(response.content.decode('utf-8'))#当解码之后的页面有乱码说明用response.test()猜错了解码方式，则应该改成response.content.decode('utf-8')
    text = response.content.decode('utf-8')
    soup = BeautifulSoup(text, 'lxml')
    conMidtab = soup.find('div', class_='conMidtab')
    tables = conMidtab.find_all('table')
    for table in tables:
      trs = table.find_all('tr')
      for index, tr in enumerate(trs):
            tds = tr.find_all('td')
            city_td = tds
            if index == 0:
                city_td = tds
            city = list(city_td.stripped_strings)
            temp_td = tds[-2]
            min_temp = list(temp_td.stripped_strings)
            data = all_data.append({'city': city, 'min_temp': int(min_temp)})
            # print({'city':city,'min_temp':int(min_temp)})

我看的是之前的视频，以前的版本和现在bar应该有些改变是吧
