Revision as of 13:40, 11 February 2013

Monday (2/11/13)

Warmup:

  1. Login to CodingBat
  2. Complete 6 exercises from List-1
  3. If you have already completed them, then complete 1 exercise from List-2

Agenda:

  • Finish coding the War card game
  • Reading/commenting code exercise
  • Quiz on the War code on Wednesday (2/13/13)
  • List & String Practice Problem
    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. You can test our your code using the following file: Media:Names.txt

Wednesday - Friday (2/6/13 - 2/9/13)

Agenda:

  • Course Request Forms
  • Demo Advanced Python List Exercises
  • More List Documentation
  • War Card Game 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
  • 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)

Monday - Tuesday (2/4/13 - 2/5/13)

Agenda:

  • Complete Advanced Python List Exercises by Wednesday (2/6/13)
  • If you are done with all the exercises, then do the following:
    1. Read up on the rules of blackjack
    2. Draw a simple flowchart for a simple blackjack game (Vegas rules). Be sure to use the flowchart symbols
  • 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.
      • 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)
