[ivonne-hernandez]

What (if any) features are you implementing?

• I refactored the category_benefits dictionary.

Just one small thing, the description's default message for tanf and ssi doesn't start with a space . Never mind if it doesn't matter. Thanks.

Great catch! Thank you for your feedback Ming! I went back and removed the empty space from all of the programs' descriptions default_message.
