Congratulations to Troy and Carlson who finished with flying colors.

Dominick is yet to choose a day, but he still has plenty of time for that.

Type of software to be discussed in the guest lecture of next Tue.

• a Hangman implementation
• word jumble implementation
• the Nim game implementation
• bubble sort implementation
• voters' bubble sort implementation (more to come soon)
• basic scalable patterns implementation
• guess the number in ten tries (computer does)
• magic squares implementation (will use the matrix code from the patterns problem)

First final exam tomorrow Thu Aug 03: Troy Grosfield.

Key to eliminate apprehension on an exam: pretend you're someone else.

Subject: A201/A597 Final Exam

As discussed yesterday in class the final exam in A201/A597 this semester
will consist in solving a problem chosen at random from a set of announced
problems in class in 25 minutes. Exams could start as early as this Thu in
lecture or lab. You should feel free to send me a note to reserve the time
that would work best for you.

As discussed yesterday (in class) and demonstrated through selected clips
from the Chris Farley show, such a circumstance might induce nervousness--
and to a significant extent. You should not worry. For, as we further show
in class today, if you just abandon your fears study hard and let yourself
go, things are bound to go well. And I'll have additional Farley clips to
demonstrate these ideas on hand today (clips plus selected outtakes).

Here's the list of the problems, which we will discuss in class this week
extensively (along with more details on the exam per se).

    1. Hangman
    2. Word Jumble
    3. Guess the number in ten tries (computer does)
    4. Sort a list of numbers
    5. Sort list candidates (data from a file) by the number of votes received
    6. Object-oriented game of Nim
    7. Matrices and magic squares
    8. Scalable patterns (A, Z, 4, M, Q, R, W and such).

 
Please let me know if you have questions. See you in class.

... Adrian

P.S. Times available: this Thu (lecture, lab), Mon (lecture, lab), Wed and
Thu (lecture, lab) next week. Let me know what times you prefer. Tue Aug 8
next week we have a guest lecture Krishna Kumar from Microsoft will give a
presentation on Managed DirectX and the new XNA (to be released Nov 2006).
I might also make a brief presentation on the Blender gamekit.

Details forthcoming by e-mail soon.

Here's the simplest example that illustrates the point of yesterday's lecture:

class Player(object):
    def __init__(self,name):
        self.name = name 
        self.points = 0;
    def points(self): # watch out! the name points has already been taken...
        print "Adding one point to", self.name
        self.points += 1

p = Player("Larry") # this assigns an int value to p.points 
p.points() # this amounts to invoking the int (impossible!!)

The key here is to not use the same name for the instance method as for the instance variable.

Today I am available for office hours 9:00am-10am and 11:00am-1:00pm in LH201D.

10:00-11:00am I am in my office but in a teleconference.

Office hours today: 9:10-10:10am, and 12noon-1:15pm in LH201D.

Basically 10:20am-11:50am I will be unavailable.

Homework Seven is slowly slowly making it into individual mailboxes now.

Also, PostEm now has complete grade reports for everybody (section is A201-7056).

Reading assignment for this week: chapter 8.

Here is an older homework assignment and a set of notes to guide us today.

Lab and lecture notes for today posted, along with Homework Six (due Thu).

In lab we will review a set of four new Alice chapters.

You should receive an e-mail message indicating your current course status.

Most everybody is doing very well but,

• the remaining part of the semester will differ from student to student
• based on the specific strengths and/or weaknesses

that you may have demonstrated thus far.

This coming week Homework Six will be posted (will be due Thursday).

Also, we go back to Alice for a few days.

Subject: late today 30 mins

Sorry for missing everybody today by 30 minutes. I came back from
Indianapolis late and got to Lindley only at 1:59pm. I saw the note
on the board and I have the list of names, I am in my office now. I
had to be in Indy this morning for a meeting with the publisher for
a text we have developed for the Fall (with Addison-Wesley). 

Unfortunately I left Bloomington a bit late, got there late, and left 
late again (for Bloomington this time), arrived back here late, missed 
everybody, was in fact ready to teach for 45 minutes, until 2:45pm, when 
our class ends, it wouldn't have been bad to do at least 45 minutes today?! 

But since I was late, and I could not announce anyone, I guess it's fine for 
us to not have a class today. ?! 

I don't need to be anywhere outside Bloomington until the end of the
summer session. So this (I apologize for it) won't happen again. The
exam is tomorrow 1:30pm in class, first part, then in lab 3:30-5:15pm.

Please review problems you have seen and worked on in class, for the
homework and the lab assignments. If you have any questions or need any
help please let me know. Thanks again and sorry for missing everybody.

Lecture Notes for today will be posted in the evening, if we develop new code.

If we just discuss old code there will be no new notes.

The lecture will be used to catch up.

Perhaps code developed in class will be posted here after the lecture.

(No new code will be developed, old code not discussed yet will be reviewed.)

(Please use PostEm A201-7056 to find your grades).

Program we might discuss today:

def average(scores):
    sum = 0
    for score in scores:
        sum += score
    return sum/float(len(scores))

scores = []
score = raw_input("Enter: ")
while score != 'done':
    scores.append(int(score))
    print "Current average is: ", average(scores)
    score = raw_input("Enter: ")
print "Thank you for using this program."

Example code for Homework One with comments and whatnot.

Grades updated, can be checked here. Grading scale as below:

0-54.99	55-65.99	66-67.99	68-69.99	70-75.99	76-77.99	78-79.99	80-85.99	86-87.99	88-89.99	90-95.99	96-up
F	D	D+	C-	C	C+	B-	B	B+	A-	A	A+

Here's another program we will discuss in class today:

user = raw_input("Number:")
sum = 0
count = 0
while user != "done":
    sum = sum + float(user)
    count = count + 1
    print sum/count
    user = raw_input("Number:")

Homework Two posted as well.

Office hours from now on: MTWR 10am-12noon.

Grades so far will be posted tonight.

Here's the old Homework Zero material from the Spring of 2005.

(It contains the queen problem as well as many numerous other thoughts and problems along with comments.)

Labs will be MR 10am-12noon in BH108 from now on.

Here's more information about our class (and A201 in general this summer).

Notes for this class as taught in:

• First Summer 2006
• Spring Semester 2005
