Tell us what’s happening:

I’m failing 20 , 23 and 24 and I don’t know exactly why. F12 console only tells me there is an assertion error.

Your code so far

Hi @Exikluk

Here is an assertion error.

AssertionError: 
     B  F  E   \n     u  o  n   \n     s  o  t   \n    [160 chars]t   ' != '
      B  F  E  \n     u  o  n  \n     s  o  t  \n     i [147 chars] t  '

Looks like your function has a spacing issue.

I’m not sure which is which. But one line is the expected string, the other is the actual string produced by your function.

Happy coding

actual then expected, assertions are by default like that
