#Here is the Python program you requested.

    """View decorator for processing standard url keyword args: Intercepts the
    keyword args path or article_id and looks up an article, calling the decorated
    func with this ID.
    Will accept a func(request, article, *args, **kwargs)
    NB! This function will redirect if an article does not exist, permissions
    are missing or the article is deleted.
    Arguments:
    can_read=True and/or can_write=True: Check that the current request.user
    has correct permissions.
    can_delete and can_moderate: Verifies with wiki.core.permissions
    can_create: Same as can_write but adds an extra global setting for anonymous access (ANONYMOUS_CREATE)
    deleted_contents=True: Do not redirect if the article has been deleted.
    not_locked=True: Return permission denied if the article is locked
    Also see: wiki.views.mixins.ArticleMixin
