Food Magnate Simulation Programming Tasks

for the sake of my sanity I choose to complete these tasks in the more pythonic version I created

Task 1

This question refers to the subroutine modify_company within the Simulation class.

Currently, the user is prompted to enter a value of 1, 2 or 3, but if nothing is entered by the user, the program responds by outputting a blank line.

Change the subroutine modify_company to present the user with an additional choice: "C. Cancel". If the user enters anything other than 1, 2, 3 or an upper-case 'C', the menu should be redisplayed repeatedly until either 1, 2, 3 or C is selected. If 1, 2 or 3 is entered, modify_company should behave as normal. If an upper-case 'C' is entered, the program should output 'Operation Cancelled', and modify_company should return without executing any additional code.

Test that the changes you have made work:

run the Food Magnate Sim program
leave the first prompt blank, to indicate a normal-sized settlement
enter D at the next prompt for default companies
enter 3 for 'modify company'
enter AQA Burgers when prompted for a company name
enter X at the first prompt of the 'modify company' submenu
enter C at the second prompt of the 'modify company' submenu

Task 2

This question refers to the subroutine get_random_location within the Settlement class.

This subroutine generates a random location within the bounds of the settlement that is used to position a new household. Currently, there is no mechanism for ensuring that a new household is not assigned the location of an existing household.

Change the subroutine get_random_location to ensure that only unoccupied locations are returned. Prior to returning the location, a check should be made to determine whether the location is already occupied by a household. If it is already occupied, a new location should be generated, repeatedly if necessary.

Test that the changes you have made work:

modify the Settlement constructor in the following ways:
change _x_size = 1000 to _x_size = 3
change _y_size = 1000 to _y_size = 3
change _initial_households = 250 to _initial_households = 8
run the Food Magnate Sim program
leave the first prompt blank, to indicate a normal-sized settlement
enter D at the next prompt for default companies
enter 1 for 'display details of households'

Task 3

This question refers to the subroutine _display_events_at_day_end within the Simulation class. Currently, there is a 25% chance of an event occurring when an end of day is run (which calls the _display_events_at_day_end subroutine). Modify the subroutine so that the following logic applies instead: NB The function RANDOM() returns a real number from 0 to 1.

Test that the changes you have made work:

run the Food Magnate Sim 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'
repeat until each of the events (including no events) have been triggered
