如何使用列表在 python 上制作一个简单的 3x3 迷宫？

Question

我有这个项目，我必须制作一个基本的基于文本的 maze/adventure 游戏。到目前为止，这是我的代码，但很奇怪。我希望它能够随时退出并在输入不在选择范围内时显示 'Please choose an available direction' 。我知道我的代码是错误的，但我不知道该怎么办。有人可以帮我吗？谢谢！

顺便说一句，我用这个 link 作为指南 http://programarcadegames.com/index.php?chapter=lab_adventure

maze_list = []
maze = ['Available Directions: East', None, 1, None, None]
maze_list.append(maze)
maze = ['Available Directions: East, South', None, 2, 3, 0]
maze_list.append(maze)
maze = ['Available Directions: West', None, None, None, 1]
maze_list.append(maze)
maze = ['Available Directions: North, East', 1, 4, None, None]
maze_list.append(maze)
maze = ['Available Directions West, South', None, None, 5, 3]
maze_list.append(maze)


current_tile = 0
print(maze_list[0])


done = False
while done != True:

    print('')
    print(maze_list[current_tile][0]) # available directions
    move = raw_input('Which direction will you take?' )
    if move == 'East' or 'east' or 'EAST':
        next_tile = maze_list[current_tile][2]
        current_tile = next_tile

        print('')
        print(maze_list[current_tile][0])
        move = raw_input('Which direction will you take? ')
        if move == 'South' or 'south' or 'SOUTH':

              next_tile = maze_list[current_tile][3]
              current_tile = next_tile
              print('Nice')


              if move == 'Quit' or 'quit' or 'QUIT':
                print('Better luck next time. \nGoodbye.')
              elif move == 'West' or 'west' or 'WEST':
                next_tile = maze_list[4]
                current_tile = next_tile
              else:
                print('Please choose an available direction')

          elif move == 'Quit' or 'quit' or 'QUIT':
            print('Better luck next time. \nGoodbye.')
          elif move == 'North' or 'north' or 'NORTH':

我开始这样做是为了尝试一件有趣的事情。（下面这个可能不是答案，但无论如何......发布它）

但让我告诉你一件事：该指南非常 "low" 质量（是的，我可能太苛刻了，但是嘿！只是一个意见）。即使这是初学者编程，我也没有理由不介绍字典和其他常用工具。

我在第 10 点或第 11 点停了下来，继续我到目前为止的内容。基本上目标是根据你给我的网站上的数字移动到厨房。如果您有兴趣了解更多或有任何问题，我很乐意回答。

祝你好运:)

import sys
room_list = [] 

#2,3,4
room_list.append(["Bedroom 2, You can go north and east.",3,1,None,None])

#10++ Here I started writing my own code... :)

directions = {"North":1,"East":2,"South":3,"West":4}

#11
while not done:

    print("\n"+room_list[current_room][0])
    q = "0"
    valid_choice = False

    while not valid_choice:

        while not directions.get(q.title()):
            if q != "0":
                print("Try again...")
            q = raw_input("Where do you want to go? (North,East,South or West) Or Quit (Q)")
            if q.title() == "Q":
                print("You pressed Q. Exit")
                sys.exit()

        next_move = directions.get(q.title()) 
        next_room = room_list[current_room][next_move]

        if next_room:
            valid_choice = True
            current_room = next_room                
        else:
            print("You can't go that way")
            q = "0" # reset question

    if current_room == 5:
        print("\nYou are in: "+room_list[5][0])
        done = True

Q: Hi, thanks for this! If you don't mind me asking, what do the directions = {"North":1,"East":2,"South":3,"West":4} and the directions.get(q.title()) do?

directions = {"North":1,"East":2,"South":3,"West":4} 在这种情况下是字典。它包含键（北、东、南、西）及其对应的值（1、2、3、4）。因此，当您键入 directions["North"] 时，您实际上得到的值是 1.

但是还有另一种获取值的方法，那就是使用 directions.get() 函数。当您这样做并且密钥不存在时，返回 None。例如。 directions.get("monkey") = None 但 directions.get("East") = 2。这在我们使用 while not 循环时非常有用。在用户输入有效内容之前，q 将是 None 并重复问题。

最后 q 是问题返回的字符串。而 str.title() 函数 returns 首字母大写的字符串。例如。 "hellOOO".title() = "Hellooo" 这就是为什么您可以输入 "easT" 并仍然得到 "East" 的原因，这是您需要制作 directions.get 的值("East") 工作。

Q: one more question (sorry i'm quite new at this), if i wanted to add a quit function, where would i insert it? i tried placing it in lines before else statements but i get errors.

我补充了：

import sys

和

if q.title() == "Q":
    print("You pressed Q. Exit")
    sys.exit()
