The template folder defaults to templates\; so you should rename include to templates.

I have the following structure in my project : \myapp application.py \include
hello.html so the folder myapp contains application.py and the folder include. the folder include contains hello.html. the following code : application.py

#!/usr/bin/python 2.7.6
# -*- coding:utf-8 -*-
import os
import sys
from flask import Flask,render_template
import psycopg2
app = Flask(__name__)
@app.route('/')
def fihoum():
    conn = psycopg2.connect(database="carto", user="postgres",
           password="daed5Aemo", host="192.168.12.54")
    cur = conn.cursor()
    cur.execute("SELECT * FROM carto.\"BADGES_SFR\"")
    rows = cur.fetchall()
    return render_template('hello.html', titre="Données du client
   BADGES_SFR !",mots=rows)
if __name__=="__main__":
    app.run(host=os.getenv('IP', '0.0.0.0'), 
            port=int(os.getenv('PORT',5000)),debug=True)

the following code hello.html :

<!DOCTYPE html>
<html>
    <head>
        <meta charset="utf-8" />
        <title>{{ titre }}</title>
    </head>
    <body>
        <h1>{{ titre }}</h1>
        <ul>
        {% for mot in mots %}
            <li>{{ mot }}</li>
        {% endfor %}
        </ul>
    </body>
</html>

THE PROBLEM: Whene I run the program application.py I have this mistake : jinja2.exceptions.TemplateNotFound

TemplateNotFound: hello.html thanks for your help
