WikiPL provides a Python programming environment hosted in a MediaWiki server. Each article in the wiki contains either a Python function or a class named as the article's title. Moreover, the article can contain the source code, documentation, unit tests, development edition, permissions, and form elements for the parameters of the function. Users can view the documentation or edit and execute the source code. Execution can happen either on the local computer, on a remote server, or in the browser (through Pyjamas). Code in one article can be invoked by another article through regular function calls, without any changes to the syntax of the Python language. It also offers a package that imports article code into a local Python namespace for offline development.
