跳出 Try/Except While 循环

Question

我有一个 while 循环，它检查自动收报机是否存在，如果不存在，它允许用户重试，但同时如果使用类型退出，它将退出程序。这里的代码

ticker = input("Ticker : ")
while True:
    try:
        web.DataReader(ticker, 'yahoo',start, end)
        print('Ticker exists')
    except Exception as e:
        responce = input('That Ticker does not exist. Try Again? Type exit to quit')
        if responce.lower() == exit:
            break
        else:
            pass

当您键入 exit 时，我无法让它中断。

Answer 1

response = input('That Ticker does not exist. Try Again? Type exit to quit')
    if response.lower() == "exit":
        break

您只是缺少引号 "exit"
