파이썬 : 글로벌 이름 'xxx'가 정의되지 않았습니다.

Question

작은 텍스트 모험을 만들고 싶었습니다.

You can go to an old school and have the option to go inside by damaging an old door or by finding an open window. There is a dog in the basement and if you take the door, he wakes up because of the noise and kills you instantly when you go into the basement. But if you go through the window, he should be asleep when you enter the basement and wake up then.

그는 이미 (school_dogawake = True) 다음 모든 것이 잘 작동하지만, 그가하지 않은 경우 school_dogawake이 False하고 지하에 True로 설정해야하지만, 오류가 발생 일어 났을 경우 NameError: global name 'school_dogawake' is not defined (가 전역) .

def initialize(): 
    school_dogawake = False 
    school() 

def school(): 
    global school_dogawake 
    choice = raw_input("How to enter the school? ") 
    if choice == 'break door': 
     school_dogawake = True 
     school_floor() 
    elif choice == 'window': 
     school_floor() 

def school_floor(): 
    global school_dogawake 

    if school_dogawake: # this works! 
     print school_dogawake # prints True 
     print "The dog was awake." 
    else: # global name 'school_dogawake' is not defined 
     print "The dog is waking up." 
     school_dogawake = True 

initialize() 

Answer 1

당신은 initialize에서 global 누락, 그래서 초기

school_dogawake = False 

하면 해당 기능 로컬 입니다.

def initialize(): 
    global school_dogawake 
    school_dogawake = False 
    school() 

그러나, global는 일반적으로 나쁜 생각 :이 간단한 수정 프로그램입니다. 대신 state 사전 주위에 통과 고려 :

def initialize(): 
    state = {'dog awake': False} # set initial state 
    school(state) 

def school(state): 
    ... 
    state['dog awake'] = 'True' # update state as required 
    ... 
    school_floor(state) 

def school_floor(state): 
    if state['dog awake']: # test current state 
     ...
