用python爬虫爬到的天气预报，使用smtplib和email模块可以发送到邮箱，使用schedule模块可以定时发送。以下是代码～

#导入模块
import requests
from bs4 import BeautifulSoup
import smtplib
from email.mime.text import MIMEText
from email.header import Header
import schedule
import time

#输入邮箱发件人、收件人以及邮箱的授权码
account = str(input('请输入发件人邮箱地址：'))
password = str(input('请输入邮箱授权码：'))
receiver = str(input('请输入收件人邮箱地址：'))

#建立天气网爬虫，爬取天气信息
def weather_spider():
    #模拟浏览器：
    headers={
        'user-agent':'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.98 Safari/537.36'
        }
    url='http://www.weather.com.cn/weather/101211001.shtml'
    #数据获取：
    res=requests.get(url,headers=headers)
    res.encoding='utf-8'
    #数据解析：
    soup=BeautifulSoup(res.text,'html.parser')
    #数据提取：
    tem1= soup.find(class_='tem')
    weather1= soup.find(class_='wea')
    tem=tem1.text
    weather=weather1.text
    return tem,weather

#发送邮件的代码
def send_email(tem,weather):
    global account,password,receiver
    mailhost='smtp.qq.com'
    qqmail = smtplib.SMTP()
    qqmail.connect(mailhost,25)
    qqmail.login(account,password)
    content= '衢州的天气是：\n'+tem+weather
    message = MIMEText(content, 'plain', 'utf-8')
    subject = '今日天气预报from python'
    message['Subject'] = Header(subject, 'utf-8')
    try:
        qqmail.sendmail(account, receiver, message.as_string())
        print ('邮件发送成功')
    except:
        print ('邮件发送失败')
    qqmail.quit()

#建立任务
def job():
    print('开始一次任务')
    tem,weather = weather_spider()
    send_email(tem,weather)
    print('任务完成')

#定时发送
schedule.every().day.at("7:00").do(job) 
while True:
    schedule.run_pending()
    time.sleep(1)
