Python Flask Render Text from Variable like render_template

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?

You can use render_template_string:

>>> from flask import render_template_string
>>> render_template_string('hello {{ what }}', what='world')
'hello world'

Actually you can call jinja2 render function directly:

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

When not working with flask, this is useful

you can use from_string

template = "text {{ hello }}"
print app.jinja_env.from_string(template).render(hello='Hello')

>> text Hello

Taken from What's the easiest way to escape HTML in Python.

import cgi

return cgi.escape(rendered)
