This a problem set for you to work through [1]

This is a problem set. Some of these are easy, others are far more difficult. The purpose of these problems sets are:

  1. to build your skill applying computational thinking to a problem
  2. to assess your knowledge and skills of different programming practices


What is this problem set trying to do[edit]

This problem set is linked to modeling and Simulation. We are applying our knowledge and understanding of dictionaries, conditionals, computational thinking & problem-solving and iteration.

Please understanding how this simulation works.

The Problem[edit]

This problem set has four different parts.We are starting simple and working our way up to more complexity.

Part 1[edit]

  1. An ant is a little insect that generally isn't very cute and likes to eat things.
  2. An ant has an ID number. Each ID number is unique
  3. An ant has a boolean state named life: alive or dead
  4. An ant has a boolean state named mode : looking for food, bringing food to nest

Create this model in python using a dictionary data type. Please save your file as ants.py. Please have two ants. Warning! Because this dictionary is going hold many ants, we need to use a nested dictionary. Please print the full dictionary for each ant.

Part 2[edit]

  1. An ant should ALSO have a boolean state "moving" : yes or no
  2. An ant should ALSO have an attribute "movement direction": North, South, West, East

Add these two states to each of your ants. Like before, please print the full dictionary for each ant.

Part 3[edit]

  1. An ant should ALSO have a state which describes it's current position in X,Y coordinates:
    1. current position x : an integer between 0 and 100 for X position
    2. current position y : an integer between 0 and 100 for Y position

Add these these two states to each of your ants. Like before, please print the full dictionary for each ant.

How you will be assessed[edit]

Your solution will be graded using the following axis:


Scope

  • To what extent does your code implement the features required by our specification?
  • To what extent is there evidence of effort?

Correctness

  • To what extent did your code meet specifications?
  • To what extent did your code meet unit tests?
  • To what extent is your code free of bugs?

Design

  • To what extent is your code written well (i.e. clearly, efficiently, elegantly, and/or logically)?
  • To what extent is your code eliminating repetition?
  • To what extent is your code using functions appropriately?

Style

  • To what extent is your code readable?
  • To what extent is your code commented?
  • To what extent are your variables well named?
  • To what extent do you adhere to style guide?

# ========= PART ONE ============
ants =  {
    
    1: {
    "life": "alive",
    "state": "looking for food"
    },
    2: {
    "life": "alive",
    "state": "bringing food to nest"
    }
}

print("Ant 1 is: ", ants[1])
print("Ant 2 is: ", ants[2])

# ================ PART TWO ===============

ants =  {
    
    1: {
    "life": "alive",
    "state": "looking for food",
    "moving": "yes",
    "movement direction": "North"
    },
    2: {
    "life": "alive",
    "state": "bringing food to nest",
    "moving": "yes",
    "movement direction": "North"
    }
}

print("Ant 1 is: ", ants[1])
print("Ant 2 is: ", ants[2])
