I am new to the Python language and having a dickens of a time understanding OOP programming. I can understand the scipt prior
on page186.py with no problem that is from the perspective of procedural programming, however. cannot understand
the script page210.py. I don't understand how the program flows beyond the return (AthleticList....call to the function
AthleticList(list). How does the sanitize(time_string) function get called. I realize that there is a function call in the print(james... that at its end calls the sanitize
function by calling the .top3() function to ge the lowest times.
