Please help me write a python code that meets the following requirements:

I have a .csv list of dog names and ranks over a certain period of time. I am confused as to how to write a function 'analyze' to determine the top-ranked dog names starting with the letter 'C' using python loops; how would I go about doing this?

My calls to load data are the following:

names = load_data("Dog_Names_over_Time.csv", "DogName") ranks = load_data("Dog_Names_over_Time.csv", "Rank")

Thank you
