31| import csv
32| with open("mega.csv","w", newline='') as f:
33| fw = csv.writer(f)
34| for m in mega:
http://syw2l.org
35| fw.writerow(m)
36| print("done")

The file mega.csv should contain:

08/31/2018,7,18,29,32,45,17,3\n Free
09/04/2018,2,7,25,35,44,3,3\n
09/07/2018,8,10,41,54,68,10,2\n
09/11/2018,15,30,51,62,67,19,2\n
...
11/20/2018,10,16,31,42,66,10,3\n eBook

Now let's write a program to open the mega.csv file and count the number of times that a white ball has
been drawn. Looking at the data the 5 white balls are at index 1-5. Remember that the csv.reader
returns a list of strings, and we need to convert them to integer ball numbers.

1| import csv
2| try: Edition
3| ball = int(input("enter ball number to count>> "))
