Disclaimer: This code is not tested. I am just giving you a ballpark idea of how to approach this.

I suggest you use blueprints in combination with an extension like Flask-Babel. For example, you can do something like:

views.py

mysitebp = Blueprint('mysitebp',__name__)

Then in your application package (usually __init__.py) , you can do:

__init__.py

from mysite.views import mysitebp
app = Flask(__name__)
app.register_blueprint(mysitebp,url_prefix='/en/',template_folder='en')
app.register_blueprint(mysitebp,url_prefix='/fr',template_folder='fr')

..and so on

Your directory structure could look like:

mysite/
__init__.py
views.py
templates/
    base.html
    404.html
    en/
        en.html
    fr/
        french.html

Flask-Babel would help you translate the 404.html etc.
