Web
接口
如果你需要脚本、爬虫或者报告任务按需执行，一个简单的解决方案是直接构建一个
Web
接口，人们可以登录进去并点击按钮执行任务。
Python
有很多不同的网络框架供你选择，
所以使用哪一个框架以及花费多少时间在
Web
接口上完全取决于你。
一个简单的方式是使用
Flask-Admin
（
https://flask-admin.readthedocs.org/en/v1.0.9/
），这是一
个基于
Flask
网络框架（
http://flask.pocoo.org/
）构建的管理站点。
Flask
是一个微框架，这
意味着它并不需要太多的代码上手。在依照快速开始指引（
http://flask.pocoo.org/docs/0.10/
quickstart/
）创建并运行了网站后，你只需要在
Flask
应用程序中创建一个视图来执行任务。
确保任务可以在完成时用其他的方式通知用户或你（邮件、通知等），因为
它不太可能及时地完成并给出一个合适的
Web
响应。同样确保在任务开始
时通知用户，这样他们不会发出一连串的让任务开始运行的请求。
另外一个流行并且经常使用的
Python
框架是
Bottle
（
http://bottlepy.org/docs/dev/index.
html
）。
Bottle
的用法类似于
Flask
，如果用户点击了按钮（或做了其他简单的操作），
Bottle
用视图来执行任务。
Python
开发者使用的一个大型
Python
网络框架是
Django
