Click on the Home tab above.

Today’s discussions:
What is python programming language?

What is computer programming? What is an algorithm?

    You need paper and pen/pencil.

  • Work with a partner to do the following activity: Find the largest and the smallest in a set of numbers.
  • Your teacher will hand you a handful of folded papers with a number on each of them.
  • Open only two papers at a time while the rest of them should stayed folded.

    • minmax5

  • Write down the steps or draw a diagram to show how you calculate both numbers.
  • Switch your paper with a different group.
  • Can you follow the steps? Write comments and suggestions about it.
  • Summarize your strategy in one short paragraph in edmodo.com (You can do this part for homework).

Homework:

  1. Send me an email with your parents email address: the email subject should have student name, class period and class name:
    Example:
    Subject: 6th period – Python – Your Name
  2. Discuss the class policy with your parents.
  3. Visit edmodo.com and reply to the “Introduce yourself” post.

Loops: Compound Interest

Classwork:
CompoundInterest_YI.py: Use a while loop to calculate how many years it would take to have an accumulated total of at least $1,100 at an interest rate of 1.2% when $1,000 is deposited in a savings bank account.

Homework:
CompoundIntTable_YI.py: Use a while loop to show how the investment increases as the accumulated total becomes at least $1,100 at an interest rate of 1.2% when $1,000 is deposited in a savings bank account.

Welcome to THE INVESTMENT TABLE

year  1  interest for this year  12.0  total accumulated up to this year  1012.0
year  2  interest for this year  24.144000000000005  total accumulated up to this year  1024.144
year  3  interest for this year  36.433727999999974  total accumulated up to this year  1036.433728

Number of years for the investment of $1000 to reach at least a value of $1,100 with an interest rate of 1.2% is  8

Pi Day Activity

Screen Shot 2014-03-13 at 7.53.55 AM
Monday is Pi Day – We will have a pi-day activity ending on Monday
Starting today we are celebrating Pi day by preparing to write a program to do one of the following:
1. Calculate the digits of Pi to highest possible precision
2. Illustrate how Pi is used in a circle.
3. Illustrate how Pi can be applied.
4. Illustrate how Pi was discovered by telling an interactive story.

The programs will be judge based on ingenuity and/or creativity.
NOTE: You can use online resources to help you develop your program. There are good algorithms online. You can not use already written programs.
Include any links used for your resources.

If you like to memorize some of the digits of pi, there will be a competition on Friday. The student who can write the most digits without any help, get a small trophy.

Homework: Explore and investigate the uses and history of pi.
Tomorrow you will tell me what your program you will work on.

Algorithm: Tic-Tac-Toe Functions

February 9th, 2016

Tic Tac Toe program is due on 2/11/16.

Keep in mind programming style tips we have been discussion since the beginning of the year:
1. Documentation: COMMENTS – the header and a short line in each function definition.
2. Naming: use relevant names for variables and functions.
3. Test all possible scenarios to make sure every part of the program executes successfully.

Screen Shot 2016-02-11 at 8.13.56 AM

NOTE: TO MAKE IT MORE INTERESTING AND INVITING TO THE PLAYER, MAKE THE FIRST COMPUTER MOVE RANDOM. However, it should be intelligent once the game is on.

A- 1 day late
B+ 2 days late
B 3 days late
B- 4 days late
C+ 5 days late
C 6 days late
C- 7 days late
D+ 8 days late
D 9 days late
D- 10 days late
F 11 days late
0 after 11 days pass the due date

I encourage you to talk to me ahead of time if this is a problem.

These two functions can be borrowed from the author’s program:


def drawBoard(board):
    # This function prints out the board that it was passed.

    # "board" is a list of 10 strings representing the board (ignore index 0)
    print('   |   |')
    print(' ' + board[7] + ' | ' + board[8] + ' | ' + board[9])
    print('   |   |')
    print('-----------')
    print('   |   |')
    print(' ' + board[4] + ' | ' + board[5] + ' | ' + board[6])
    print('   |   |')
    print('-----------')
    print('   |   |')
    print(' ' + board[1] + ' | ' + board[2] + ' | ' + board[3])
    print('   |   |')

and

def isWinner(bo, le):
    # Given a board and a player's letter, this function returns True if that player has won.
    # We use bo instead of board and le instead of letter so we don't have to type as much.
    return ((bo[7] == le and bo[8] == le and bo[9] == le) or # across the top
    (bo[4] == le and bo[5] == le and bo[6] == le) or # across the middle
    (bo[1] == le and bo[2] == le and bo[3] == le) or # across the bottom
    (bo[7] == le and bo[4] == le and bo[1] == le) or # down the left side
    (bo[8] == le and bo[5] == le and bo[2] == le) or # down the middle
    (bo[9] == le and bo[6] == le and bo[3] == le) or # down the right side
    (bo[7] == le and bo[5] == le and bo[3] == le) or # diagonal
    (bo[9] == le and bo[5] == le and bo[1] == le)) # diagonal

Algorithm: Battleship Day 4

Continuing to prepare for the Battleship program

Classwork:

1. Write the pseudocode to handle checking if there is a ship on one of the edges. What steps would your program follow?

Suggested Classwork:

2. Write a program, Edges4_YI.py to handle the following scenario:

– a hit is found on one of the edges locations on the 3 x 3 board and based on the user’s response write the code to find the ship and sink it.

The idea at every scenario is to find a pattern so you can minimize the code and reuse it.

– Use a list of three lists with 3 items each.
– Randomly select the edges where the program will place the ship.

Reminder:

Requirements for an A:
1. Don’t forget the introduction with the rules of the game. Let the player know that the ships can only be placed horizontally or vertically.
2. The program has to be turned in on time.
3. The program must have the pygame component.
4. The program has to display at least one board.
5. The program has to handle two ships: 1 of two places and 1 of three places.
6. The program uses a smart algorithm after it finds the first occupied place.
7. The program’s quality of design
8. The program has to run until the game is over.

What will cause a drop in the grade?
The program is not able to tell if the ships overlap.
The program is not able to recognize invalid input.(Prompt the user for valid input)
The program is not able to detect duplicate entries. (Prompt the user for valid input)
The program has no header, no documentation and no output.
The program is over due.

Short Bio:
Sean Shypula grew up in Miami, FL and from a young age was fascinated with computers and all things electronic.  In an age before the widespread use of the internet, he managed to teach himself how to write simple programs on his Commodore 64 based upon a few CS books found in a public library, bits of source code found in the back pages of Byte magazine, and a lot of trial and error.  He followed this passion into college earning a degree in Computer Engineering from the University of Florida in 2003.  After college he decided to pursue his true goal of one day being able to make video games for a living, and in 2006 earned a Master’s degree in Computer Science from DigiPen Institute of Technology in Redmond, Washington.  Sean was quickly hired by Bungie Studios, where he has happily been building the studio’s tools and infrastructure ever since.  Sean’s credits include Halo 3, Halo ODST, Halo Reach, and the soon-to-be-released Destiny, which will be the first of a long series of games and the first new franchise for the studio since gaining their independence from Microsoft in 2007.
