What You Need to Do

• Create the script hw11.py
• Make sure it obeys the rules in Rules for Homework Scripts
• Make sure the script has a hashbang line and is executable
• Move it to an an hw11 directory on pe15.cs.umb.edu

Setup On Your Machine

• Open a text editor.
  I would suggest the text editor built into the program IDLE.
• Save the file as hw11.py

Specification

• This script must contain two classes
  • Game
  • Baseball_Game
• Baseball_Game is a subclass of Game
• Game must have the following attributes
  • date
  • home_team
  • opponent
  • home_score
  • opponent_score
• All these attributes must be hidden
• Game must have the following methods
  • __init__
  • get_date
  • get_home_team
  • get_home_score
  • get_opponent
  • get_opponent_score
  • __str__
  • winner
• Baseball_Game must have the following attribute
  • winning_pitcher
• This attribute must be hidden
• Baseball_Game must have the following methods
  • __init__
  • __str__
  • get_winning_pitcher

Game Methods

__init__

• Header

  def __init__(self, date, home_team, opponent, home_score, opponent_score):

• This method should assign values to all attributes
• The attributes are hidden

gate_date

• Header

  def get_date(self):

• This method should return the value of the date attribute

get_home_team

• Header

  def get_home_team(self):

• This method should return the value of the home_team attribute

get_home_score

• Header

  get_home_score(self):

• This method should return the value of the get_home_score attribute

get_opponent

• Header

  get_opponent(self):

• This method should return the value of the get_opponent attribute

get_opponet_score

• Header

  get_opponent_score(self):

• This method should return the value of the get_opponet_score attribute

__str__

• Header

  def __str__(self):

• This method must return a string containing the values of all attributes

winner

• Header

  def winner(self):

• This method must return the name of the winning team

Baseball_Game Methods

__init__

• Header

  def __init__(self, date, home_team, opponent, home_score, opponent_score, winning_pitcher):

• This method should assign values to all attributes
• The attributes are hidden

get_winning_pitcher

• Header

  def get_winning_pitcher(self)

• This method should return the value of the winning_pitcher attribute

__str__

• Header

  def __str__(self):

• This method must return a string containing the values of all attributes

Test Code

• Your script must contain the following statements
• They should appear at the bottom of your script

game_1 = Game("2007-10-24", "Red Sox", "Rockies", 13, 1)
print(game_1)
print(game_1.get_date())
print(game_1.get_home_team())
print(game_1.get_home_score())
print(game_1.get_opponent())
print(game_1.get_opponent_score())
print(game_1.winner())
game_2 = Baseball_Game("2007-10-24", "Red Sox", "Rockies", 13, 1, "Josh Beckett" )
print(game_2)
print(game_2.get_winning_pitcher())

Output

• The output should look something like this

  2007-10-24: Red Sox 13, Rockies 1
  2007-10-24
  Red Sox
  13
  Rockies
  1
  Red Sox
  2007-10-24: Red Sox 13, Rockies 1, Winning pitcher: Josh Beckett
  Josh Beckett

Testing on Your Machine

• Open IDLE
• Use the Open command in IDLE to open hw11.py
• Under the Run menu, select Run Module
• Your output should look something like this

  2007-10-24: Red Sox 13, Rockies 1
  2007-10-24
  Red Sox
  13
  Rockies
  1
  Red Sox
  2007-10-24: Red Sox 13, Rockies 1, Winning pitcher: Josh Beckett
  Josh Beckett

Copy the Script to Unix

• Open FileZilla and connect to pe15.cs.umb.edu
• Go to your it117 directory
• Go to your hw directory
• Right-click in the whitespace inside the hw directory
• Enter hw11 in the dialog box
• Click and drag your script from the bottom left panel to the bottom right panel
• Right-click on the file and select "Permissions" from the menu
• Enter 755 in the box provided
• This will make the script executable

Testing the Script on Unix (Optional)

• Connect to pe15.cs.umb.edu using an ssh client like putty.exe (Windows) or ssh (Mac)
• Go to the directory for this exercise

  cd  it117/hw/hw11

• Run this script

  hw11.py

• You should see something like this

  2007-10-24: Red Sox 13, Rockies 1
  2007-10-24
  Red Sox
  13
  Rockies
  1
  Red Sox
  2007-10-24: Red Sox 13, Rockies 1, Winning pitcher: Josh Beckett
