Youtube user ID regexp question

[kuerbis]

Is the user/ part in a user ID url optional?

_VALID_URL = r'(?:(?:(?:https?://)?(?:\w+\.)?youtube\.com/(?:user/)?(?!(?:attribution_link|watch|results)(?:$|[^a-z_A-Z0-9-])))|ytuser:)(?!feed/)(?P<id>[A-Za-z0-9_-]+)'

Yes. For example the URL https://www.youtube.com/KoreanFilm is equivalent to https://www.youtube.com/user/KoreanFilm
