# Modelling a simple system

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

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.

## The Problem

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

### Part 1

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

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

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.

### Part 4

1. Create a fixed-count loop. The loop should range from 0 to 10.
2. Each iteration should represent one second.
3. Each iteration, print the following attributes for each ant:
1. moving?
2. moving direction?
3. alive?
4. mode?
5. current position X?
6. current position Y?

Please don't complicate this. I just want to see textual output of 10 seconds, please. Also, don't worry about updating the position of the ant. I just need you to see what 10 seconds for our model looks like.

## How you will be assessed

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