试图退出程序，进入死循环(Python)

Question

我是初学者，试图退出我在 Python 中的第一个程序，但只是陷入无限循环。不明白怎么回事。

question = input("Please enter your 'to do' list: ")
some_list = []

while True:
    if question not in some_list:
        some_list.append(question)
        question = input("Please enter your 'to do' list: ")
    else:
        print("\n\nPress enter to exit")
        print(some_list)

Answer 1

首先，永远不要使用 built is 函数作为变量。您基本上是将数字 4 分配给数字 5：4=5。这是错误的。我修好了。

question = input("Please enter your 'to do' list: ")

something = []


while True:
    if question not in something:
        something.append(question)
        question = input("Please enter your 'to do' list: ")
    else:
        print("\n\nPress enter to exit") 
        print(something)

Answer 2

question = input("Please enter your 'to do' list: ")
list = []

while True:
    if question not in list:
         list.append(question)
         question = input("Please enter your 'to do' list: ")
    else:
        input("\n\nPress enter to exit")
        print(list)
        break

Answer 3

欢迎光临！如果你想像你在其中一张印刷品中写的那样打破循环：“\n\nPress enter to exit”，你可以使用以下解决方案：

while True:
  x = input()
  if len(x) == 0:
    break

完整代码为：

question = input("Please enter your 'to do' list: ")
list = []

while True:
    question = input("Please enter your 'to do' list: ")
    if len(question) == 0:
        break
    if question not in list:
        list.append(question)

print(list)

Answer 4

question = input("Please enter your 'to do' list: ") 
alist = []

while True:
    if question not in alist:
        alist.append(question)
        question = input("Please enter your 'to do' list/type 'quit' to exit: ")
        if question=='quit': 
            break
print(alist)
