Welcome to the forum @islamqasimov

You almost got it.

The for loop needs to be a part of the .join method.

Happy coding

Hi! I have the same code but it doesn’t pass. It says: " You should call str() on each element in part using a generator expression"
Could you please explain the indentation for this for loop? is it part of the previous nested for loop or outside?
