Writing to CSV

You just read a CSV file and printed the first row. You're now ready to edit the file header and save the rows in a new .csv file. Changing the file header for shorter column names without spaces will make managing columns more manageable in the long run.

Then, you will write the header and the first row into a new CSV file named PPR-2021-Dublin-new-headers.csv.
