Chapter 11: Sections 11.1 - 11.9 / all participation and challenge activities

2) Let's continue to work on the program from HW19 assignment:

1) Allow the user to enter the message to be encrypted: function getInput should take care of it (and it should return the message the user typed in);

2) Define function buildEncryption that will build the encryption association (dictionary) and return it;

3) Define a function encrypt that will take two parameters: the message to be encrypted and the encryption association;

4) Finally, define a function main, that will: ask the user to enter the message to be encrypted (calls function getInput), then builds the encryption association (calls function buildEncryption), encrypts the message (calls function encrypt) and displays it

 		 HW 19 (due date: Wednesday, May 1st, 11:59pm):

Write a program for random substitution cipher.
Here are few key moments:
1) You need to store the information about the association of letters of the alphabet in the original (unencrypted) message, to the letters for the encryption (store this in a dictionary named ecr)
2) Your program needs to only encrypt the message, it doesn't need to get the message to encrypt from a user.
3) When the association of letters is ready, go ahead and iterate over all symbols in the message to encrypt and encrypt all the letters, ignore all other symbols (keep them as they are).
4) Our program will not understand the upper case letters, so don't forget to convert all those upper case letters to lower case

Since this textbook doesn't keep information about your work but still has some interactice practices, when you finished working on each chapter, save it as pdf file and send it to my e-mail.
Here are the instructions:
Do a right click anywhere on the page (a menu will pop-up), choose print... , then change your printer to "save as pdf", click "save". Save the three files (for three sections) as different pdfs. Send them to me as attachment along with the programming assignment.

Programming Assignment : (to be sent to my e-mail: natna20@gmail.com)
1) Turtle race: http://interactivepython.org/runestone/static/thinkcspy/Labs/lab03_01.html
2) Grab the program Turtle_frame.py .
I want to draw a frame in the graphics window and I already started writing the program. Finish drawing the frame.
3) Let's create a spiral pattern. You have several options:
      (1) start at the center of the screen (the origin)
      (2) start at one of the corners (say lower left) of the screen.
In both options, use while loop.

Idea: start with some length, say 300 pixels, length = 300
Run a while loop. At each iteration of the while loop: draw the line of length, then decrease the length, and turn 90 degrees.

Here is a possible picture of the spiral (feel free to click on it to get a larger size picture):

Chapter 9: Sections 9.5 - 9.7 / all participation and challenge activities,

2) Programming Assignment: (to be sent to my e-mail: natna20@gmail.com, by the due date)
(1) Write the program that given the list of decimal numbers data, finds:
   - the average of all negative numbers in the list data,
   - the average of all positive numbers in the list data, and
   - the average of all numbers in the list data.
Your program should display all three results clearly.
You may use any of the lists of values for data, to test your program:
data =[1,1,2,2,3,3], or data = [-1,-2,-3,-4], or data = [1,-1,2,-3,5,-4,7], or data = [1,0,-2,0,3,7,-9,10,0].
(2) Write a program that finds the sum of the positive numbers entered by the user. The program should notify the user what does it do, then the user is prompt for positive integers (while loop or for loop to use?). If the user enters a negative number, this is the signal for the while loop to stop. Don't forget to add all those positive numbers the user entered! At the end, the program should display the sum of all positive numbers entered by the user.

Extra practice (not for grade, not for submission):
consider the following program TurtleWithForLoops.py(it draws a star). Follow the comments to change it.

In-class Activity: CSI11Day5InClassActivity.pdf

Programs: qr.py, circleMath.py 		HW 5 (due date: Wednesday, February 20th, 11:59pm):

1) ZyBooks, HW05:
Chapter 5: sections 5.6-5.10 / all participation and challenge activities,

2) programming assignment: write a program to find solutions of a quadratic equation ax2+bx+c = 0. The user should be prompt for three values: a, b, and c. Then the formulae

x1 = -b - √ b2-4ac   ,   and
                    2a

x2 = -b + √ b2-4ac   .
                    2a

should be used to find the two solutions.

To test your program use the following information:
1) quadratic equation x2 + 4x + 4 = 0 has one solution: x = -2
(note that the constants a = 1, b = 4, c = 4)
therefore your program should produce both x1 = -2 and x2 = -2

2) quadratic equation x2 - 4x + 4 = 0 has one solution: x = 2
(note that the constants a = 1, b = -4, c = 4)
therefore your program should produce both x1 = 2 and x2 = 2

3) quadratic equation x2 - 2x - 3 = 0 has solutions: x = -1, 3
(note that the constants a = 1, b = 4, c = 4)
therefore your program should produce both x1 = -1 and x2 = 3

Install Python 3.7:
1) Download the distribution of the Python from here (latest release 3.7): https://www.python.org/downloads/release/python-370/ (scroll down)
This distribution includes compiler, standard libraries and a simple IDE called IDLE.

2) Install Python.
Check "add Python to the PATH" during the installation.

3) After installation you can run IDLE by clicking:
  Start -> All Programs -> Python 3.7 -> IDLE (Python GUI)
