Jinja Templates in Flask
The Jinja templating engine is one of the key building blocks of a Flask application.
With them, you can:
- Use static HTML template files to decouple routes from HTML
- Separate HTML structure from content
- Use programming constructs -- variables, conditionals, and for loops to control shown content -- in your templates
A template file (containing variables and logic) is rendered into an output file (typically HTML).
from flask import render_template @app.route('/') def index(): return render_template('index.html')
