thanks for the conmments nice work :)

No, very bad practice.

In case of error the function should raise (or propagate) an exception, not return a string.

good solution

ord function Return the ascii code point for a one-character string.

How you get this idea is a something in math or what ?

If it fails the tests, then usually that just means there's a logic error in the code. This task is about returning the length of the repeated subsection of the sequence. Your solution is missing a tiny modification in a single place to pass all tests.
