Template syntax A Tornado template is just HTML (or any other text-based format) with Python control sequences and expressions embedded within the markup: support control statements and expressions. Control statements are surrounded by {% and %}, e.g. {% if len(items) > 2 %}. Expressions are surrounded by {{ and }}, e.g. {{ items[0] }}. Control statements main thread.
