[[File:square.png|right|frame|This a problem set for you to work through <ref>http://www.flaticon.com/</ref>]]

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

# to build your skill applying computational thinking to a problem
# 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]].

Please [http://www.netlogoweb.org/launch#http://ccl.northwestern.edu/netlogo/models/models/Sample%20Models/Biology/Ants.nlogo understanding how this simulation works].

== The Problem ==

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

=== Part 1 ===

# An ant is a little insect that generally isn't very cute and likes to eat things. 
# An ant has an ID number. Each ID number is unique
# An ant has a boolean state named '''life''': alive or dead
# 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 [https://www.programiz.com/python-programming/nested-dictionary nested dictionary]. Please print the full dictionary for each ant. 

=== Part 2 ===

# An ant should ALSO have a boolean state "moving" : yes or no
# 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 ===

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

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

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?
