初学python小白一枚,到分析数据一步还可以正常print,加上可视化就会报错,麻烦大神帮忙看看是什么问题导致,谢谢!
报错信息在截图,代码如下:
# encoding: utf-8
import requests
from bs4 import BeautifulSoup
import html5lib
from pyecharts.charts import Bar
ALL_DATA = []
def parse_page(url):
headers = {
'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36',
'Referer': 'http://www.weather.com.cn/forecast/'
}
response = requests.get(url,headers = headers)
text = response.content.decode('utf-8')
soup = BeautifulSoup(text,'html5lib')
conMidtab = soup.find('div',class_= 'conMidtab')
tables = conMidtab.find_all('table')
for table in tables:
trs = table.find_all('tr')[2:]
for index,tr in enumerate(trs):
tds = tr.find_all('td')
if index == 0:
city_td = tds[1]
else:
city_td = tds[0]
city = list(city_td.stripped_strings)[0]
temp_td = tds[-2]
min_temp = list(temp_td.stripped_strings)[0]
ALL_DATA.append({"city":city,"min_temp":int(min_temp)})
# print({"city":city,"min_temp":int(min_temp)})
def main():
urls = [
'http://www.weather.com.cn/textFC/hb.shtml',

for url in urls:
parse_page(url)
# 分析数据
# 根据最低气温进行排序
ALL_DATA.sort(key = lambda data:data['min_temp'])
data = ALL_DATA[0:10]
cities = list(map(lambda x:x['city'],data))
temps = list(map(lambda x:x['min_temp'],data))
# 可视化
# pyecharts
chart = Bar("中国天气最低气温排行榜")
chart.add('',cities,temps)
chart.render('temperature.html')
