Subject: [PATCH] friend_fcuntion

I was stuck on def people_who_like_color(people, color) and def get_color_dict(people); I forgot to define the list or dict first;
Or sometimes I used the wrong label for them. I checked the output when I test it and also ask ChatGPT to identify what's wrong with my code.
