instance of Template you get back a new template object that provides a method called render() which when called with a dict or keyword arguments expands the template. The dict or keywords arguments passed environment with the default settings and a loader that looks up the templates in the templates folder inside the yourapplication python pack- 7 age. Different loaders are available and you can also write on the language level. For example Jinja2 treats the non- breaking space as valid whitespace inside expressions which requires knowledge of the encoding or operating on an Unicode string. For more details
