Food Magnate Simulation questions

You have been given the code for the Food Magnate Simulation. Using that code, answer the following questions:

N.B. this code was rewritten from the original by me during the summer so it conforms to the Python style guide. Most names have been recased from PascalCase to snake_case

1. State the name of an identifier for:

   1. An attribute in the Settlement class that is only accessible to subclasses of Settlement.
      • N/A, because this is Python and all attributes are accessible by all objects (the 'consenting adults' principle). However, an attribute that is considered non-public by convention is Settlement._x_size
   2. A subclass
      • LargeSettlement
   3. A subroutine from the Company class that cannot be called from outside the Company class.
      • Again, N/A due to the 'consenting adults' principle. However, a subroutine of Company that by convention is considered non-public is the static method Company._get_distance_between_two_outlets
   4. A string method called from the company_index subroutine in the Simulation class
      • str.lower

2. '10' Add an option to run the simulation for many days (>1)

   1. Your PROGRAM SOURCE CODE for the amended
      • Diff, source
   2. SCREEN CAPTURE(S) showing the results of the requested change
      • <script id="asciicast-e5Cj9i2Ob9QM3zmPUkpyd1ToL" src="https://asciinema.org/a/e5Cj9i2Ob9QM3zmPUkpyd1ToL.js" async>

3. '11' Add a new SmallSettlement class and an option to create a small settlement in the simulation launch menu.

   1. Your PROGRAM SOURCE CODE for the amended
      • Diff, source
   2. SCREEN CAPTURE(S) showing the results of the requested change
      • <script id="asciicast-lzwMKAPq7GPrsUgd2DZqMuQgJ" src="https://asciinema.org/a/lzwMKAPq7GPrsUgd2DZqMuQgJ.js" async>
   3. '1' This question refers to the subroutine _process_add_households_event and the _display_events_at_day_end subroutine within the Simulation class.

   Modify the subroutine _process_add_households_event in the Simulation class. Rename the subroutine to _process_add_remove_households_event and all calls to it so that they use the new identifier. Instead of just adding 1-4 houses to the settlement, there should be a 30% chance that 1-4 houses will leave the settlement instead.

   The message displayed by the subroutine should be changed so that when houses are removed, it says removed from instead of added to.

   Modify the subroutine _display_events_at_day_end in the Simulation class. The subroutine should always call the newly modified subroutine _process_add_remove_households_event.

   Test the changes that you have made work:

   • run the Skeleton Program
   • leave the first prompt blank, to indicate a normal-sized settlement
   • enter D at the next prompt for default companies
   • enter 6 for 'advance to next day'
   • enter 1 for 'display details of households'
   • repeat this until households are removed from the settlement (and are added)
