1. #Exercise 2: Write a program that categorizes each mail message by
2. # which day of the week the commit was done. To do this look for lines
3. # that start with “From”, then look for the third word and keep a running
4. # count of each of the days of the week. At the end of the program print
5. # out the contents of your dictionary (order does not matter).
6. #Sample Line:
7. #From [email protected] Sat Jan 5 09:14:16 2008
