write a function:

Names(path):

that reads from a file at location path and returns a dictionary mapping from column names to lists containing the data in those columns. The format of the file is a csv file. The first line is a comma separated set of string names for the columns contained in the file. The function will accumulate a dictionary mapping from year to the list of years, from name to the list of names (in the same order), and from count to the list of counts (in the same order).Convert year and count to integers.
