A dictionary is initialized as dictionary = If a list in Python is similar to an array in Java, then a dictionary in Python is similar to a Map (i.e., HashMap or TreeMap). The element of the list in row r and column c can then be accessed: list In Python, an n-by-m list of zeros (which is similar to an n-by-m array in Java or C) is initialized as list = for y in range(m)] To do this, you'll need to know how to use Python's list and dictionary data structures, as the board passed into your constructor is a list of dictionaries. Next, implement the methods "isAlive(self, row, col)" which returns True if the cell at the given row and column is alive and False otherwise, "setAlive(self, row, col, tf)" which sets the cell at the given row and column to have the value tf, "getNumRows(self)" which returns the number of rows in the game board, and "getNumCols(self)" which returns the number of columns in the game board. Define instance variables "rows", "cols", and "grid". Now that we know this, write the code for Life's constructor. Thus, instead of needing to define our instance variables outside of the constructor and setting their values inside of it, we can simply write "self.variable = value" in our constructor and have "self.variable" serve as an instance variable which can be used by any other methods in the class. One of the first things you should understand about Python is that, unlike Java, it allows you to both define and set the value of instance variables in the same line. In Python, classes have the following format: class : What you're looking at is a class called "Life". Open the file "life.py" in the "part1" subfolder of the "gameoflife" folder you downloaded. And to just get super meta for a second, a consequence of this is that Game of Life can simulate ITSELF! (#Conwayception) In fact, these rules are so powerful that they actually allow Conway's Game of Life to be Turing Complete, which roughly means that we could perform any computation within the game that a standard computer could (though they would be painfully slow). These extremely simple rules give rise to some incredibly complex and beautiful patterns, as illustrated here: Any dead cell with exactly three living neighbors becomes alive.Any living cell with more than three living neighbors dies.Any living cell with exactly two or exactly three living neighbors remains alive.Any living cell with fewer than two living neighbors dies.Each cell changes from one time step to the next according to the following rules: A given cell's neighbors are those cells directly above, below, left, or right of the cell, plus with the cells diagonally adjacent to it (the cells touching its diagonals). This entry was posted in DevLog on by admin.Our "Game of Life" board will be an n-by-n grid of square cells, each of which can be either "alive" or "dead". Most of the work in the short term will be ensuring the code works as a standard Python package. Other tools such as rendering engines could import this package. The Autumn CA package provides Cellular Automata computing through NumPy arrays. I ran into some difficulty getting my Cython code to build correctly as this was outside the scope of the video.Īfter some searching I found the solution was to update the manifest file to include the code: Conclusion The process of using Virtual Environments, Cookie Cutter and Tox integration testing tools was well explained. This talk from Dave Forgac was a great resource: Usually I would dump my code in a folder and call it a day but for this project I decided to try and follow standard Python practice as much as possible. The code is still quite rough around the edges with plenty of TODO statements to be found. The code for the project can be found in this Git Hub repository: Using Python I have implemented Conway’s Game of Life.
