Answer 1

Do you asking about removing errors? If yes, add proper identation.. If you don't know learn about identation..

About logic,
They may be many ways, trying yourself finding logic is important..
According to your logic, first find if input contains youtube.com Or youtu.be/

str has method find() which return index of substring otherwise returns -1 so on -1 go to replace 2nd link or replace first link

edit:
Yagub!
alternatively you have count("sub_str") to find how many times sub_str in in.
index("sub_str") method which return index of substring, if not found raise error..
you can find just last index of / and find next all charecters and print, type of link don't matters..

hope it helps.. try to implement again...

Answer 2

It has identation mistakes
First you need find which type of the link , then try to replace.
See if input is
https://www.youtube.com/watch?v=2345789
Then it prints as it is.
It don't raise error..
According to your logic no need try catch. Replace just replaces if any found as first argument otherwise its no effect.
