A Python translation of Austin Henley's original Java homework task, shared with permission and with thanks to the original author. 

Skeleton Python code is provided that runs a basic digital pets game with actions such as Eat and Exercise. Tasks are provided that require students to extend the game by adding more pet species, more actions, and editing the main() program code, using key principles of object-oriented programming, including: 

  • changing attribute access modifiers (name mangling)
  • implementing and using a constructor method
  • implementing and using getters and setters
  • using inheritance to create subclasses
  • abstract methods
  • static methods
  • linking objects through association (composition)

Code is commented and the tasks are embedded in the comments.

I am currently not providing Task 2 answer code publicly as this is an assessed homework but can send via email upon request.

P.S. I re-uploaded the resources as text files instead of .py files, downloaded them, and was able to open the .zip file. So this should work now.

@BecciPeters, the issue is with downloading .py files specifically. I was using Safari on a MacBook Pro.

@Philippa Lewty I also tried to download the file and it was empty. However the .py code files are uploaded, so I hope CAS moderators can work out what is going wrong. Meanwhile, you are welcome to email me for the resources on my profile address.

Currently the compressed file is empty when you download it - is this correct?
