在用户输入列表中满足条件时停止while循环

Question

我是否正在尝试创建一个寄存器，该寄存器将用户输入附加到列表中，中断并返回到用户“输入数据”的提示，但仅在输入字符串“done”时停止。

userinput = input("Please Input price: ")
price = [userinput]

    while True:
       if price.append(userinput) is True:
        print(price)
       if price.append("done") is True:
        break

    print(price)

Answer 1

userinput = input("Please Input price: ")
price = []

while userinput != "done":
    price.append(userinput)
    print(price)  # This appears to serve as debugging only, you will see the whole list as it is grown
    userinput = input("Please Input price: ")

print(price)
