I hate Google!

This'll probably work:

accent-test/accent-test.py:
#####################################################################
#!/usr/bin/env python3

import os
from jinja2 import Environment, FileSystemLoader

PATH = os.path.dirname(os.path.abspath(__file__))
TEMPLATE_ENVIRONMENT = Environment(
    autoescape=False,
    loader=FileSystemLoader(os.path.join(PATH, 'templates')),
    trim_blocks=False)

def render_template(template_filename, context):
    return
TEMPLATE_ENVIRONMENT.get_template(template_filename).render(context)

def create_index_html():

    # put the list into a dictionary for rendering
    context = {
                'title': "accent-test",
                'french': 'année',
                'french1': 'année',
              }

    # render the template to html
    print ("Content-type: text/html\n\n")
    print (render_template('accent-test.jnj', context))

def main():
    create_index_html()
