I think it's Graph Search because there isn't any graphs in Facebook. That is my opinion. I don't use social media.
It does not matter its is just a view and is not required to store data
I've added my own code in a picture below. I didnt really notice any error, which would cause problems in your code. The main issues I had with your code is purely readability. You should start using the format function along with the curly brackets to concatenate variables into strings. You should also start doing even += 1 instead of even = even + 1. I also tweaked your range function. Simply putting n makes it much easier to read and understand.
The colors should match the attitude the business would like to present.
