在不同輸出的終端上運行相同的程序

Question

所以我是一個絕對的初學者，通過Zed Shaw的Learn Python The Hard Way進行工作。 由於某些原因，當我運行一個程序時，我隨機獲得了不同的輸出。下面是我的代碼的一部分以及一些不一致的輸入/輸出。我已經連續多次嘗試過這種方式，有時代碼會正常工作，並調用下一個函數，有時會跳過大部分代碼。

這裏是我的代碼不能始終如一地運行......

def bear_room():  
    print "There is a bear in here." 
    print " The bear has a bunch of honey." 
    print " The fat bear is in front of another door." 
    print " How are you going to move the bear?" 
    bear_moved = False 

    while True: 
     next = raw_input(">") 

     if next == "take honey":       
      dead("The bear looks at you and slaps your face off.") 
     elif next == "taunt bear" and not bear_moved: 
      print "The bear has moved from the door. You can go through it now." 
      bear_moved = True 
     elif next == "taunt bear" and bear_moved: 
      dead("The bear gets pissed off and chews your leg off.") 
     elif next == "open door" and bear_moved: 
      gold_room() 
     else: 
      print " I have no idea what that means." 

下面是一些不一致的輸出... 這裏我運行該程序，並使用「左」輸入的提示。

Theresa-Beckers-MacBook-Pro:Summer 2013 Python leafgirl12$ python ex35.py 
You are in a dark room. 
There is a door to your right and left 
Which one do you take? 
>left 
You stumble around the room until you starve. Good job! 

在這裏，我立即做了同樣的事情，這次它運行，但輸出是不同的。

Theresa-Beckers-MacBook-Pro:Summer 2013 Python leafgirl12$ python ex35.py 
You are in a dark room. 
There is a door to your right and left 
Which one do you take? 
>left 
There is a bear in here. 
The bear has a bunch of honey. 
The fat bear is in front of another door. 
How are you going to move the bear? 

我知道在C++中創建新的變量時，它可以堆棧VS堆的問題，但我續找到在同一臺計算機上的Python功能的任何答案。我還重新輸入了我的代碼，以防出現一些我看不到的縮進錯誤。有幾次，當我繼續輸入「take honey」時，我能夠得到正確的輸出結果，但這隻能用一半的時間，而「嘲諷的熊」還沒有起作用。它只是直接傳遞給其他人。 有什麼想法？這有道理嗎？

Answer 1

「左」或「右」後面的空格將使您餓死。 :)

Answer 2

從看the code for this exercise開始，你必須在其中一次嘗試時出現拼寫錯誤「左」，請注意，這可能是不必要的大寫或開頭或結尾處的意外空間。

這裏是有問題的代碼：如果您在「左」的準確，按回車，你應該總是進入熊市客房類型

def start(): 
    print "You are in a dark room." 
    print "There is a door to your right and left." 
    print "Which one do you take?" 

    next = raw_input("> ") 

    if next == "left": 
     bear_room() 
    elif next == "right": 
     cthulhu_room() 
    else: 
     dead("You stumble around the room until you starve.")
