import requests

import urllib2

headers = {‘Content-Type‘: ‘application/json;charset=utf-8‘}
api_url = "https://oapi.dingtalk.com/robot/send?access_token=37e23308d1b84eb4ac34566e03c4c4e74bxxx7xxxxxxxxxxx"
##从钉钉机器人设置中拷贝  
def msg(text):
    json_text= {
     "msgtype": "text",
        "at": {
            "atMobiles": [
                "132xxxx1280"
            ],
            "isAtAll": False
        },
        "text": {
            "content": text
        }
    }
    print requests.post(api_url,json.dumps(json_text),headers=headers).content

hearders = "User-Agent","Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/60.0.3112.113 Safari/537.36"

url = "https://tianqi.moji.com/weather/china/guangdong/shenzhen"    ##要爬去天气预报的网址
par = ‘(<meta name="description" content=")(.*?)(">)‘    ##正则匹配，匹配出网页内要的内容

##创建opener对象并设置为全局对象
opener = urllib2.build_opener()
opener.addheaders = [hearders]
urllib2.install_opener(opener)

##获取网页
html = urllib2.urlopen(url).read().decode("utf-8")

##提取需要爬取的内容
data = re.search(par,html).group(2)
msg(data)

拷贝脚本时请去掉注释
运行脚本：

python weather.py 
{"errcode":0,"errmsg":"ok"}

钉钉群收到消息如图：

做计划任务：

# crontab -e
no crontab for root - using an empty one
30 8 * * * /usr/bin/python /root/script/weather.py 2> /dev/null > /dev/null

每天早晨8:30自动推送天气预报到钉钉群
