Activity 4.3.1: Terminus - Part 2 [portable] (1080p)

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

steps = 0 max_steps = len(grid) * len(grid[0]) * 2 # prevent infinite loops

path = right_hand_rule_navigation(grid_example, start, goal) print("Path taken:", path) activity 4.3.1: terminus - part 2

while (row, col) != goal and steps < max_steps: # Right-hand rule: try to turn right first for turn in [1, 0, 3, 2]: # right, straight, left, u-turn new_dir = (direction + turn) % 4 dr, dc = dirs[new_dir] new_row, new_col = row + dr, col + dc if (0 <= new_row < len(grid) and 0 <= new_col < len(grid[0]) and grid[new_row][new_col] == 0): # Move row, col = new_row, new_col direction = new_dir path.append((row, col)) visited.add((row, col)) break steps += 1

Could you provide a little more context so I can develop the feature accurately for you? grid: 2D list (0=free, 1=wall) start, goal: (row,
