We shouldn't pass `_` with that name.  If you need to pass ugettext as an argument, do this:
```
from django.utils import translation
...
get_transcripts_from_youtube(youtube_id, settings, translation)
...
def get_transcripts_from_youtubye(youtube_id, settings, i18n):
    _ = i18n.ugettext
    _("Hello!")
```
`_` as an argument name is too confusing.
