Python循环不会继续

问题描述：

程序应该不断询问用户输入标题并查看“你想继续（是/否）”的答案吗？是Y.相反，它只询问用户一次。有人可以帮我弄清楚，而循环不会继续。谢谢！Python循环不会继续

#!/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()

因为你'return' while循环 – JCVanHamme

你'return'是'while'环路的一部分。 Unindent它。 – Matthias

'return listOfReviews'使函数'obtainListOfReviews（）'返回存储在'listOfReviews'中的值，并将其分配给'main（）'中的变量'listOfReviews'。 –

答

你有一个错误的缩进你行 “回归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

Python循环不会继续
