the error is here, the `!` has to go before the equal for the ‘different from’ comparison

but you should actually reset the step, and add one single line with a `print`, you should print the comparison between `char` and a space `" "` (you are comparing to an empty string now)

I spent a couple hours on this, and it is the dumbest issue. the SPACE has to go in between the ’ ’ so you put the cursor in between them, and hit the space key. Also, make sure the line is the 2nd line.
