python获取天气数据

无意中发现了www.tianqi.com这个天气查询网站，这个网站结构统一，并且没有在robot.txt中规定相关规则，所以我编写了一个脚本用来获取指定地点的实时天气，主要用于学习编程技巧，请不要恶意爬取数据！

import requests  
from bs4 import BeautifulSoup
#获取www.tianqi.com的天气,参数：地名拼音
def data_of_tianqi(addr):
    response = requests.get("https://www.tianqi.com/"+addr+"/")
    soup = BeautifulSoup(response.text, 'html.parser')
    tag_dd = soup.find_all(name='dd')
    tag_span = soup.find_all(name='span')[0]
    temp = str(soup.find_all(name='b')[0])[3:-4]#温度
    city_html = BeautifulSoup(str(tag_dd[0]), 'html.parser')
    city = str(city_html.find_all(name='h2'))[5:-6]#城市
    week = str(tag_dd[1])[17:-5]

    weather_and_temp = str(tag_span)[9:-7].split('</b>')
    weather = weather_and_temp[0]#天气
    temp = str(soup.find_all(name='b')[0])[3:-4]#实时温度
    temp_from_to = weather_and_temp[1]#温度范围
    shidu = str(tag_dd[3]).replace("</b>","").replace("</dd>","").split("<b>")[1]#湿度
    fengxaing = str(tag_dd[3]).replace("</b>","").replace("</dd>","").split("<b>")[2]#风向
    ziwaixian = str(tag_dd[3]).replace("</b>","").replace("</dd>","").split("<b>")[3]#紫外线
    other_info = str(tag_dd[4])[57:-12].replace('</h5><h6>','<br/>').replace('</h6><span>','<br/>').split('<br/>')#空气质量、PM、日出、日落
    info = []
    info.append(city)
    info.append(week)
    info.append(weather)
    info.append(temp)
    info.append(temp_from_to)
    info.append(shidu)
    info.append(fengxaing)
    info.append(ziwaixian)
    info.append(other_info)
    return info
data = data_of_tianqi("nanjing")
print(data)
