Tell us what’s happening:
Hello, when finalizing my code I have two tests that fail and I can’t seem to understand why. Both errors, 23 and 24, tell me to fix my spacing as shown in the example output. I looked at my code and made sure all the requirements were met, double lines in between each category. I have asked AI to fix it but it still doesn’t work. Someone please help me I am very confused.
Your code so far
