Project structure:
- file with python code at the root
-- template / template.html
-- includes / years.html

file template.html

<!doctype html>
<html lang="ru">

<head>
    <title>123</title>
</head>

<body>

    {% block year %}
    {% endblock %}

</body>
</html>

years.html file

{% extends '../template/template.html' %}
{% block year %}
    {% for i in years %}
        {{ i }}
    {% endfor %}
{% endblock %}

python:

from jinja2 import Environment, DictLoader, Template, FileSystemLoader
file_loader = FileSystemLoader('includes')
env = Environment(loader=file_loader)
template = env.get_template('years.html')
years_list = [1992, 1993, 1994]
out_render = template.render(years = years_list)
print(out_render)

python crashes on adding a dictionary over the years to the template and says that it cannot find template.html:
TemplateNotFound: ../template/template.html
Tell me, what am I doing wrong?

Add a second folder to use as templates:

from jinja2 import Environment, DictLoader, Template, FileSystemLoader
file_loader = FileSystemLoader(['templates', 'includes'])
env = Environment(loader=file_loader)
template = env.get_template('years.html')
years_list = [1992, 1993, 1994]
out_render = template.render(years = years_list)
print(out_render)

and in the template just inherit{% extends 'template.html' %}
