Answer 2

Check this pattern instead:

r'(?i)(http.//|https.//)*[A-Za-z0-9._%+-]+\.\w+'

Answer 3

I tried this one and it works fine for me.

(?:http(?:s)?:\/\/)?(?:www\.)?(?:youtu\.be\/|youtube\.com\/(?:(?:watch)?\?(?:.*&)?v(?:i)?=|(?:embed|v|vi|user)\/))([^\?&\"'<> #]+)

Answer 4

I know I'm like 2 years late to the party, but I was needing to write something up anyway, and seems to fit every test case that I can throw at it. Should be able to reference the first match ($1) to get the ID. Matches the http, https, www and non-www, youtube.com, youtu.be, /watch? and /watch.php? on youtube.com (youtu.be does not use these), and it supports matching even when there are other variables in the URL string (?t= for time, ?list= for playlists, etc).

(?:https?:\/\/)?(?:youtu\.be\/|(?:www\.|m\.)?youtube\.com\/(?:watch|v|embed)(?:\.php)?(?:\?.*v=|\/))([a-zA-Z0-9\_-]+)

Answer 5

Based on so many other regex; this is the best I have got:

((http(s)?:\/\/)?)(www\.)?((youtube\.com\/)|(youtu.be\/))[\S]+

Answer 6

• You're missing www in your regex
• The second \. should optional (since both youtu.be and youtube are valid)
• + in your regex allows for one or more of (youtube\.com|youtu\.be), not one or more wild-cards
  You need to use a . to indicate a wild-card, and + to indicate you want one or more of them.

Try:

^(https?\:\/\/)?(www\.youtube\.com|youtu\.?be)\/.+$

Test.

If you want it to match URLs with or without the www., just make it optional:

^(https?\:\/\/)?((www\.)?youtube\.com|youtu\.?be)\/.+$

If you want www.youtu.be/... to also match, put the optional www. outside the brackets:

^(https?\:\/\/)?(www\.)?(youtube\.com|youtu\.?be)\/.+$
