python获取Yahoo天气数据并发送邮件通知

共三个模块

getweather.py #获取天气信息
smtpmail.py #发送邮件
reporter.py #主程序入口，定时发送邮件

• 仅为练手项目

Ubuntu后台运行

虚拟机中新安装一个Ubuntu Server，以下为配置过程

sudo -i  #提升权限
sudo apt-get update  #更新软件列表
sudo apt-get upgrade  #更新软件
python -v #查看python版本(没有...)
sudo apt install python3  #安装python3
sudo apt-get install python-pip  #安装pip
sudo pip install --upgrade pip  #升级pip
cd /  #移动到根目录
mkdir pyweather  #新建目录pyweather
cd pyweather  #移动至pyweather文件夹
vi reporter.py  #新建并编辑py文件
cat reporter.py  #确认是否有误
vi smtpmail.py
cat smtpmail.py
vi getweather.py
cat getweather.py
ls  #确认文件
setsid python reporter.py  #常驻后台运行
history  #回顾配置过程

后来才发现邮件中的时间不对，需要改时区

date -R #确认时间
dpkg-reconfigure tzdata  # 选择时区
date -R #再次确认
