Detecting the browser language in Python Flask

Question

I need to get the browser language with Python Flask. I have tried to use:

request.headers.get('languages')

This however returns None.

I tried whoer.net and it returned it-IT for my browser language. How can I detect the browser language with Python Flask ?

Answer 1

Check out Werkzeug's LanguageAccept data structure, or just try something like this to get a best match:

supported_languages = ["en", "nl", "it"]
lang = request.accept_languages.best_match(supported_languages)

If you need more than that, then check out Flask-Babel.
