- everything inside a function must be indented
- a try and the corresponding except and optional else must all be indented to the same level
- the code that might cause an exception must be between the try and the except
- the code inside the try section must be indented further than the try itself

Courses Plus Student 456 Pointsthanks for your help but i understand the first 2 but i am struggling to understand your 3rd bullet point what is the code that causes the exception Thanks

And ValueError belongs with the except statement.
And don't forget to do what the challenge said when you have an exception.

If an answer isn't helping you then you should go back and leave a comment to your original question rather than posting your question again. You've posted several duplicates to multiple code challenges.
