我的朋友和我正在使用Python 2.7创建一个简单的基于文本的游戏。
为了开始游戏，我创建了一个系统，其中有三个保存文件可用（例如save1.txt），其中包含不同游戏状态（即位置，库存）的信息。要加载此文件，我首先要求用户决定加载有效文件（否则他们将启动新游戏）然后加载文件。在任一选项之后，应该停止提示的循环。
while loadchoice == 0:
savefile = raw_input('Would you like to load a savefile? Y/N ')
if savefile.lower() == 'y':
which = raw_input("1, 2, or 3?")
if which == '1' or which == '2' or which == '3':
loadchoice = 1
load(which)
print "You awaken"
else:
loadchoice = 0
if savefile.lower() == 'n':
loadchoice = 1
print "You have started a new game."
player.location = 0
然而，当我运行它并尝试输入文件时，我得到一个无限循环。看起来我可以加载文件并开始新游戏，但是，我不认为变量loadchoice和player.location（对我创建的类实例的引用）相应地更改。
此问题不仅影响无限循环，而且没有player.location我无法在游戏中稍后切换区域。
例如，这是三个起始房间的代码：
#Every time the room level branches out, a new digit is added to player.location
while player.location != '-1':
while player.location == '0':
print "You awaken."
print "Press Enter to continue"
print "You must find them."
print "\n"
print "\n"
player.location = '1'
#1s
while player.location == '1':
act = raw_input(">")
options()
roomitems = []
#Paths
if act.lower() == 'n' or act.lower() == 'north':
player.location = '11'
if act.lower() == 's' or act.lower() == 'south':
player.location = '12'
elif act.lower() not in possible_actions and act.lower() in possible_directions:
print "That's not a way you can go!"
#10s
while player.location == '11':
act = raw_input(">")
options()
roomitems = []
#Paths
if act.lower() == 'northeast' or act.lower == 'ne':
player.location == '111'
if act.lower() == 'northwest' or act.lower == 'nw':
player.location == '112'
if act.lower() == 'south' or act.lower == 's':
back()
elif act.lower() not in possible_actions and act.lower() in possible_directions:
print "That's not a way you can go!"
无论我如何调整，我都无法更换房间。我认为这个问题源于前一段代码所具有的相同问题。如果是这种情况，我应该在while循环中修复什么？如果这是两个不同的错误，我可以就这两个错误提出建议吗？
感谢您提供任何帮助！
根据@ chris-sc给出的建议，我为更改房间的代码创建了以下测试用例：
------------------------首先尝试解决问题----------------- ----
place = '0'
description = ' '
possible_actions = []
possible_directions = ['n', 'north', 's', 'south', 'e', 'east', 'w', 'west', 'ne', 'northeast', 'se', 'southeast', 'nw', 'northwest', 'sw', 'southwest', 'd', 'down', 'u' 'up']
while place != '-1': #The overarching condition that continues the game
while place == '0':
print "The has started."
place = '1'
#1s
while place == '1':
act = raw_input(">")
desciption = "FIRST ROOM"
print desciption
#Paths
if act.lower() == 'n' or act.lower() == 'north':
place = '11'
if act.lower() == 's' or act.lower() == 'south':
place = '12'
elif act.lower() not in possible_actions and act.lower() in possible_directions:
print "That's not a way you can go!"
#10s - down any path from the first room. These are all the possible 2nd rooms, hence two digits.
while place == '11': #You went North
act = raw_input(">")
description = "YOU WENT NORTH"
print description
#Paths - the ways you can go from this room
if act.lower() == 'northeast' or act.lower == 'ne':
place == '111' #A third room
if act.lower() == 'northwest' or act.lower == 'nw':
place == '112' #Another possibile choice for a third room
if act.lower() == 'south' or act.lower == 's':
place = place[:-1] #Going back up the path by removing the last digit
elif act.lower() not in possible_actions and act.lower() in possible_directions:
print "That's not a way you can go!"
while place == '12': #You went South
act = raw_input(">")
description = "YOU WENT SOUTH"
print description
#Paths
if act.lower() == 'north' or act.lower == 'n':
place = place[:-1] #Going back up the path by removing the last digit
elif act.lower() not in possible_actions and act.lower() in possible_directions:
print "That's not a way you can go!"
#100s
while place == '111':
description = "NORTHEAST"
print description
act = raw_input(">")
if act.lower() == 'southwest' or act.lower == 'sw':
place == place[:-1]
elif act.lower() not in possible_actions and act.lower() in possible_directions:
print "That's not a way you can go!"
while place == '112':
description = "NORTHWEST"
print description
act = raw_input(">")
if act.lower() == 'southeast' or act.lower == 'se':
place == place[:-1]
elif act.lower() not in possible_actions and act.lower() in possible_directions:
print "That's not a way you can go!"
这种尝试的成功：
place从1更改为11，从1更改为12 description在place更改时发生变化
未解决的问题：
if语句输入适当的命令，我也无法访问任何三级房间，即111或112 place == place[:-1]语句中列出的命令，我也无法通过if返回这是向前迈出的一步！但是，我不知道最重要的问题是什么。有时变量会在while循环中重新分配，但有时则不会。 谢谢@ chris-sc为您提供帮助！我会继续调试！

我稍微修改了你的代码，以python3的形式工作。我只是注释掉了播放器类的用法和load（）函数。另外，我添加了loadchoice变量的初始化。通过这些修改，代码运行得很好。
loadchoice=0
while loadchoice == 0:
savefile = input('Would you like to load a savefile? Y/N ')
if savefile.lower() == 'y':
which = input("1, 2, or 3?")
if which in'123':
loadchoice = 1
#load(which)
print("You awaken")
else:
loadchoice = 0
if savefile.lower() == 'n':
loadchoice = 1
print("You have started a new game.")
#player.location = 0
这使我们有了这样的假设：必须在load（） - 函数内部或更改player.location属性时更改loadchoice-variable。所以继续看看那里。
这是调试代码的常用方法，只需使用注释减少代码直到它工作，并逐步检查注释的代码部分，直到它再次中断。这将指出你的错误所在。

在更新的示例中，您有一些逻辑错误。让我们进行11：
while place == '11': #You went North
act = raw_input(">")
description = "YOU WENT NORTH"
print description
#Paths - the ways you can go from this room
if act.lower() == 'northeast' or act.lower == 'ne':
place == '111' # <<<<<===== CARE
if act.lower() == 'northwest' or act.lower == 'nw':
place == '112' # <<<<<===== CARE
if act.lower() == 'south' or act.lower == 's':
place = place[:-1] #Going back up the path by removing the last digit
elif act.lower() not in possible_actions and act.lower() in possible_directions:
print "That's not a way you can go!"
在这里，您有时会混合==（比较）和=（分配）。看看我在代码段中使用# <<<<<===== CARE标记的行。
类似地，在房间111和112中，您再次进行比较，而不是分配您想要的新房间号。
while place == '111':
description = "NORTHEAST"
print description
act = raw_input(">")
if act.lower() == 'southwest' or act.lower == 'sw':
place == place[:-1] # <<<<<===== CARE
elif act.lower() not in possible_actions and act.lower() in possible_directions:
print "That's not a way you can go!"
while place == '112':
description = "NORTHWEST"
print description
act = raw_input(">")
if act.lower() == 'southeast' or act.lower == 'se':
place == place[:-1] # <<<<<===== CARE
elif act.lower() not in possible_actions and act.lower() in possible_directions:
print "That's not a way you can go!"
通常，在调试此类问题时减少冗余代码是个好主意。
在你的情况下，不同房间（或地方）背后的逻辑是相同的，所以为什么不先测试一条可能的路线（从1到11到111）。如果此路由按预期工作，则可以添加分支。
通过这种方式，您可以限制错误的可能位置，并且还可以更容易地看到解释器不会向您显示的逻辑错误。
