O exemplo de Python fornecido modifica a rota /index que foi introduzida na primeira etapa do tutorial.

<a href="create-coursework-assignment.html">Create a CourseWork Assignment</a>

Adicione um modelo HTML para representar um destino no seu site. Essa página representará o conteúdo que será anexado à sua atribuição CourseWork.

<!-- /webapp/templates/example-coursework-assignment.html -->
<h1>CourseWork assignment loaded!</h1>
<p>You've loaded a CourseWork assignment! It was created from an external web page.</p>

Crie um novo arquivo de módulo do Python para processar as rotas relacionadas ao CourseWork. No exemplo mostrado, é coursework_routes.py. Adicione as três rotas a seguir. Observe que você preencherá parte do conteúdo mais tarde.
