What's the first arg to split()? It appears to be a single blank char. How does that work to split upon tab chars?
It's a space enclosed within single quotes. It tells split to split on whitespace, e.g., \t, \n, space.
That is a dangerous thing to do. it works for your example data, but it will break on real word data where you will have LAST names like Van Winkle and CITYs called New York.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
