私はこのミニテキストゲームをPythonのチュートリアルに使用しています.4番ドア/ボールト機能を使用してプレーヤーにコードを尋ね、正しく入力された場合は使用する変数の値が変更されます3番目のドアを開くための鍵として。ボールトコードが正しく与えられたときに変数の値が変更されても、私はまだドアを開けません。

誰でも手伝ってもらえますか？

Pythonの出会いvaultの内部haskey = int(1)が、それはあなただけvaultの内部を見ることができますhaskeyと呼ばれる新しいローカル変数を作成します。あなたは、その関数内でhaskeyと表示されたときに、ファイルの先頭に宣言するグローバルhaskeyを意味することをPythonに伝える必要があります。 vaultの先頭にglobal haskeyを追加すると、これを行うことができます。すなわち：

def vault(): 
    global haskey 
    while True: 
     print "There is a security code for this door. Enter code:" 
     code = raw_input("> ") 
     ...
