Activity 4.3.1: Terminus - Part 2 Repack May 2026

It sounds like you're referring to a specific activity or module — possibly from a textbook, an online course (like zyBooks, CodeHS, or Project STEM), or a game-based learning platform. “Terminus” often appears in exercises where you navigate through a grid or solve a puzzle using loops and conditionals.

row, col = start path = [(row, col)] visited = set() visited.add((row, col))

# Terminus - Part 2: Right-Hand Rule Navigation # Assumes a grid with obstacles (1 = wall, 0 = open) def right_hand_rule_navigation(grid, start, goal): """ Navigate from start to goal using the right-hand rule. grid: 2D list (0=free, 1=wall) start, goal: (row, col) tuples """ # Directions: 0=North, 1=East, 2=South, 3=West dirs = [(-1, 0), (0, 1), (1, 0), (0, -1)] direction = 1 # start facing East activity 4.3.1: terminus - part 2

Could you provide a little more context so I can develop the feature accurately for you?

if (row, col) == goal: print(f"Goal reached in {steps} steps!") return path else: print("Goal unreachable or loop detected.") return None grid_example = [ [0, 0, 0, 0, 0], [0, 1, 1, 1, 0], [0, 0, 0, 1, 0], [0, 1, 0, 0, 0], [0, 0, 0, 1, 0] ] It sounds like you're referring to a specific

(like adding a “teleport” command, logging moves, visualizing the grid, or handling dynamic obstacles), just let me know.
