[Django]-Django-translation: How to translate languages

The following code works for me:

// settings.py
ugettext = lambda s:s
LANGUAGES = (
    ('de', ugettext('German')),
    ('en', ugettext('English')),
)

// template
{% load i18n %}
{% get_available_languages as LANGUAGES %}

{% for LANGUAGE in LANGUAGES %}
    <p>{{ LANGUAGE.0 }} - {{ LANGUAGE.1 }}</p>
{% endfor %}
