Question

Wast trying to solve the youtube task but everything except the first input worked and I don't know why

Answer 1

No problem.

Answer 2

"https://www.youtube.com/watch?v=kbxkq_w51PM".split() doesn't do anything to the string (apart from put it in a list). So pattern will never be in link.split().

I guess all the other cases follow the alternative format..?

Edit to explain:

print("hello" in "hello world!") # True
print("hello" in ["hello world!"] # False since "hello" is not an element of the list

Answer 3

But the .remove(). ?

Answer 4

The remove() isn't executed because the if returns False.

Answer 5

That makes sense.
Thank you very much!

Answer 6

Even if it were executed, it would only cause an error since "watch?=" is not an element in ["https://www.youtube.com/watch?v=kbxkq_w51PM"].

Answer 7

👌👍Thanks again
