Python - Maze Generation Assignment

Objectives

• You will create a maze generation program
• You will create Python classes that represent a MazeRoom and a Maze
• You will implement a depth-first search maze algorithm using a stack as a backtracker

Resources

• Media:Stacks.ppt
• Stack - CS Animated
• Depth-first Search
• Recursive backtracker
• Maze Designer

MazeRoom class

• Create a file named MazeRoom.py for the MazeRoom class

MazeRoom Attributes

• MazeRoom should have the following attributes with default values:
  • roomToNorth - references the a doorway to the north. A None value means that there is wall
    • Default: None
  • roomToSouth - references the a doorway to the south. A None value means that there is wall
    • Default: None
  • roomToEast - references the a doorway to the east. A None value means that there is wall
    • Default: None
  • roomToWest - references the a doorway to the west. A None value means that there is wall
    • Default: None
  • row - the row number for the Room
    • Default: -1
  • col - the column number for the Room
    • Default: -1
  • visited - a Boolean that keeps track of whether or not the room has been visited in the maze algorithm
    • Default: False

MazeRoom Methods

• MazeRoom should have the following method:
  • def __init__(self, row = -1, col = -1) - set the internal row and col attributes to be the same as the input parameters

Maze class

• Download the partially completed Maze.py for the Maze class

Maze Attributes

• numRows - an int that stores the total number of rows in your maze
• numCols - an int that stores the total number of cols in your maze
• rooms - a 2-dimensional list of Rooms

Testing

• Create a new file named MazeTest.py and execute the following code:

from Maze import *

maze = Maze()
maze.generate()
maze.print()
