Chapter 9 Exercises

Exercise 2: Write a program that categorizes each mail message by which day of

the week the commit was done. To do this look for lines that start with From,

then look for the third word and 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}

Exercise 3: Write a program to read through a mail log, build a histogram using

a dictionary to count how many messages have come from each email address, and

print the dictionary.

Enter file name: mbox-short.txt

{'gopal.ramasammycook@gmai.com': 1, 'louis@media.berkeley.edu': 3,

'cwen@iupui.edu': 5, 'antranig@caret.cam.ac.uk': 1,

'rjlowe@iupui.edu': 2, 'gsilver@umich.edu': 3,

'david.horwitz@uct.ac.za': 4, 'wagnermr@iupui.edu': 1,

'zqian@umich.edu': 4, 'stephen.marquard@uct.ac.za': 2,

'ray@media.berkeley.edu': 1}

Exercise 4: Add code to the above program to figure out who has the most

messages in the file.

After all the data has been read and the dictionary has been created, look through

the dictionary using a maximum loop (see Section [maximumloop]) to find who

has the most messages and print how many messages the person has.

Enter a file name: mbox-short.txt

cwen@iupui.edu 5

Enter a file name: mbox.txt

zqian@umich.edu 195

Exercise 5: This program records the domain name (instead of the address) where

the message was sent from instead of who the mail came from (i.e., the whole email

address). At the end of the program, print out the contents of your dictionary.

python schoolcount.py

Enter a file name: mbox-short.txt

{'media.berkeley.edu': 4, 'uct.ac.za': 6, 'umich.edu': 7,

'gmai.com': 1, 'caret.cam.ac.uk': 1, 'iupui.edu': 8}
