python问题之no direction



在爬本地建立的网页过程中,出现两次这种情况,第一次是code不在python文件中

                                                                                  第二次没有精确本地html的路径,我没有学路径的问题

复制html的本地磁盘位置,后面加上html文件名,之后全部反斜杠

D:\python\课程练习\1_2answer_of_homework\1_2_homework_required\new.html

变成  <pre name="code" class="html">D:\python/课程练习/1_2answer_of_homework/1_2_homework_required/new.html

 

Sure, 我可以为您提供一个 Python 迷宫求解器代码。该代码使用了深度优先搜索算法来解决迷宫问题。 ```python def maze_solver(maze, start, end): maze_rows = len(maze) maze_cols = len(maze[0]) solution_grid = [[0 for j in range(maze_cols)] for i in range(maze_rows)] # Check if start and end points are obstacles if maze[start[0]][start[1]] == 1 or maze[end[0]][end[1]] == 1: return "No Solution!" # Mark the starting cell in the solution grid solution_grid[start[0]][start[1]] = 1 # Define potential move directions - left, right, up, down move_directions = [[0, 1], [1, 0], [0, -1], [-1, 0]] # Recursive function to check for possible paths def solve_maze(curr_row, curr_col): # Check if the current position is the end cell if curr_row == end[0] and curr_col == end[1]: solution_grid[curr_row][curr_col] = 1 return True # Check all directions for a possible path for direction in move_directions: new_row = curr_row + direction[0] new_col = curr_col + direction[1] if (new_row >= 0 and new_row < maze_rows and new_col >= 0 and new_col < maze_cols and maze[new_row][new_col] == 0 and solution_grid[new_row][new_col] == 0): solution_grid[new_row][new_col] = 1 if solve_maze(new_row, new_col): return True # Backtracking solution_grid[new_row][new_col] = 0 return False if solve_maze(start[0], start[1]): return solution_grid else: return "No Solution!" ``` 请注意,这只是一个简单的例子实现,您可能需要进行一些修改,以使其适用于您的问题
