- """ Task: Exercise 9.3
- Write a program that categorizes each mail message by which day of the week
- the commit was done. To do this look for lines which start with “From”,
- then look for the third word and then keep a running count of each of the
- days of the week. At the end of the program print out the contents of your
- dictionary (order does not matter).
- Sample Line:
- From stephen.marquard@uct.ac.za Sat Jan 5 09:14:16 2008
- Sample Execution:
- python dow.py
- Enter a file name: mbox-short.txt
- {'Fri': 20, 'Thu': 6, 'Sat': 1}
