Description

Web2py is an open source framework for agile development of database driven web applications. Web2py is written in the Python language and is programmable in Python. Web2py has a focus on security by providing default mechanisms for validation of input and escaping of output (this prevents the most common vulnerabilities such as SQL Injections, Cross-Site-Scripting, and Insecure Direct Object Referencing). It encourages the developer to follow sound software engineering practices such as the Model-View-Controller pattern, Self-Submission of Web forms, Server-Side session, and safe handling of uploaded files.

Web2py is a full-stack framework in that it has built-in components for all major functions. Examples include:

* handling cookies, session, http request, http response
* settable RAM and disk caching
* full internationalization
* automatic logging of errors with context
* Database abstraction layer that dynamically generates SQL
* multiple compatible database backends (SQLite, MySQL, PostgreSQL, Oracle, MSSQL, FireBird and Google App Engine).

Web2py differs from other frameworks because it was originally designed as a teaching tool at DePaul University and thus has a very shallow learning curve. For this reason it is designed to be easy to set up (requires no installation) and provides a web-based interface that allows development, debugging, testing, maintenance and remote database administration without third party tools.

Web2py is built following the WSGI protocol, the latest Python protocol for communication between web server and web applications. It also provides handlers for CGI and the FastCGI protocols, and it includes the ssl-enabled CherryPy wsgiserver.
