Python調用函數

Question

我想從學習python的困難方式做一個練習，我卡在某物上。我創建了一個函數，如果其中一個語句被滿足，我想把它放在另一個函數中。這是我如何試圖做到這一點大綱：

def room_1(): 
    print "Room 1" 
    button_push = False 

    while True: 
     next = raw_input("> ") 

     if next == "1": 
      print "You hear a click but nothing seems to happen." 
      button_push = True 

     elif next == "2": 
      print "You enter room 2" 
      room_2() 

def room_2(): 
    print "Room 2" 

    while True: 
     next =raw_input("> ") 

     if next == "1" and button_push: 
      print "You can enter Room 3" 
      room_3() 

如果button_push得到滿足，那麼我會希望看到，在room_2。任何人都可以幫助我嗎？

您可以通過button_push作爲參數傳遞給下一個房間：

def room_1(): 
    print "Room 1" 
    button_push = False 

    while True: 
     next = raw_input("> ") 

     if next == "1": 
      print "You hear a click but nothing seems to happen." 
      button_push = True 

     elif next == "2": 
      print "You enter room 2" 
      room_2(button_push) # pass button_push as argument 

def room_2(button_push): # Accept button_push as argument 
    print "Room 2" 

    while True: 
     next =raw_input("> ") 

     if next == "1" and button_push: # button_push is now visible from this scope 
      print "You can enter Room 3" 
      room_3()
