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())

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

Unix Setup

• Log in to users3.cs.umb.edu
  You will be in your home directory.
• Go to your it117 directory
  

  cd it117

• Go to your hw directory
  

  cd hw

• Create a directory for this exercise
  

  mkdir  hw11

• Check that the directory was created
  

  ls

Copy the file to Unix

• Open FileZilla and connect to users3.cs.umb.edu
  You will have to connect using your Unix username and password.
• Copy the file to the to it117/hw/hw11
  

Testing the script on Unix

• Connect to
  Use an ssh client.
• Go to the directory for this exercise
  

  cd  it117/hw/hw11

• Make this script executable
  

  chmod  755 hw11.py

• Run this script
  

  ./hw11.py

• You should see
