Python Flask Render Text from Variable like render_template

Question

I know the flask function render_template. I have to give the file name of the template. But now I want to render the string of a template (that is the content of the template). That makes sense. but I don’t want to explain now why. How can I render the text of a template simply?

Actually you can call jinja2 render function directly:

jinja2.Template("I am {{ var }}").render(**kargs)

When not working with flask, this is useful
