Template syntax A Tornado template is just HTML (or any other text-based format) with Python control sequences and vulnerabilities. The correct form of escaping is context-dependent; Tornado’s templates are not aware of the syntax of HTML, JavaScript, etc, and so the template developer must sometimes explicitly apply the correct reduces the need to manually restart the server during development.
