IB Computer Science 1

Thursday - Friday (12/5/13 - 12/6/13)

Warmup:

• Text-based card game introduction warmup
  1. Create a text file that has all the names for a deck of cards (Examples: 5 of Diamonds, Jack of Clubs)
  2. Write a program that loads the text file's data into a list of strings
     • Look through Python-reading and writing files and find the the f.readlines() function
  3. Store all the strings loaded into a list of strings named deck
  4. Create 2 empty lists named p1Hand and p2Hand
  5. Deal 5 cards from the deck to p1Hand
     • Look through Python-Lists and find the list.pop() function. Read how the functions works to remove elements from a list. You can then use the list.append() function to add those elements to another list
  6. Deal 5 cards from the deck to p2Hand
  7. Print out both hands

Agenda:

• Introduction to Flow Charts
  • Media:Flowcharts.ppt
  • Draw the flowchart for the list search algorithm (finding a number in a list of numbers)
  • Draw the flowchart for the list minimum algorithm
  • Draw the flowchart for the following problem: Assume you have a single data file with 1000 random numbers from 0 to 100. Print out the frequency of each of the numbers.
• War Card "Game" Simulator Walk-through
  1. Read the War Rules
  2. On a blank piece of paper, create a flow chart for the rules and steps of War. Be sure to include the following steps:
     • Shuffle deck
     • Deal deck halves to 2 players
     • Each player reveals top card
     • Player with higher card puts both cards at the bottom of his/her deck
     • If both players' cards match, then there is "war"
       1. Both players put 3 cards face down, and reveal 4th card face up. Player with higher card takes all 10 cards
  3. We will code the War card game as a class using our flow chart

Monday - Wednesday (12/2/13 - 12/4/13)

Agenda:

• Demo Advanced Python List Exercises
• List & String Practice
  1. Assume you have a list of strings of peoples' full names in random order. Print out an alphabetized list of only the last names.
  2. Assume you have a single string containing the entire U.S. Constitution. Calculate and print out the frequency of the word "the"
     • Download the following file: Media:Constitution.txt
     • Hint: There is a useful string function converts a string to a list of words.
  3. Assume you have a single data file with 1000 random numbers from 0 to 100. Print out the frequency of each of the numbers.
     • Example code to help read in a file:

# open a text file
file = open("Constitution.txt", "r")

# read all lines in the file and save in the constitution string variable
constitutionStr = file.read()

# close the file
file.close()

print(constitutionStr)
