Python循環不會繼續

Question

程序應該不斷詢問用戶輸入標題並查看「你想繼續（是/否）」的答案嗎？是Y.相反，它只詢問用戶一次。有人可以幫我弄清楚，而循環不會繼續。謝謝！

#!/usr/bin/env python 

def main(): 

listOfReviews = obtainListOfReviews() 
displayResults(listOfReviews) 

def obtainListOfReviews(): 
listOfReviews = [] 
carryOn ='Y' 
while carryOn =='Y': 
    title = raw_input("Enter title:") 
    review = int(input("Enter review:")) 

    st = MovieReview(title, review) 
    listOfReviews.append(st) 
    carryOn = raw_input("Do you want to continue?(Y/N)? ") 
    carryOn = carryOn.upper() 
    return listOfReviews 

def displayResults(listOfReviews): 
    for r in listOfReviews: 
     print(r) 

class MovieReview: 
def __init__(self, title = " ", review = 0): 
    self._title = title 
    self._review = review 
def setTitle(self, title): 
    self._title = title 
def setReview(self, review): 
    self._review = review 
def getTitle(self): 
    return self._title 
def getReview(self): 
    return self._review 
def __str__(self): 
    return ("Title: " + str(self._title) + " \nreview: " + str(self._review)) 
main() 

Answer 1

你有一個錯誤的縮進你行 「迴歸listOfReviews」：

def obtainListOfReviews(): 
listOfReviews = [] 
carryOn ='Y' 
while carryOn =='Y': 
    title = raw_input("Enter title:") 
    review = int(input("Enter review:")) 

    st = MovieReview(title, review) 
    listOfReviews.append(st) 
    carryOn = raw_input("Do you want to continue?(Y/N)? ") 
    carryOn = carryOn.upper() 

# Correct indentation 
return listOfReviews
