Thank you all, managed to get it to work.
For those curious - I’ve been printing the result even when there was no True argument, but as it was only spaces (blank) I didn’t see it until I changed all spaces into ‘x’ 
Second thing - last test - I misinterpreted the examples and tried to put a space between result number and the ‘-’ if there was any. Deleted that part and voila.
Love y’all!!!
