虽然循环没有结束

Question

def getStocks():
    stockNames = []
    stockPrices = []
    done = 0
    while done != 1:
        stock = input('Enter Stock symbol: ')
        if stock == 'done':
            done = 1

        else:
            price = int(input('Enter Price of Stock: '))
            print("")
            stockNames.append(stock)
            stockPrices.append(price)
    return stockNames, stockPrices

问题是＆＃34;输入股票代码：＆＃34;即使在用户键入“完成”之后出现，如何在此时终止无限循环？我尝试使用break但它没有提供我正在寻找的结果

Answer 1

而不是input使用raw_input它将解决问题

def getStocks():
    stockNames = []
    stockPrices = []
    done = 0
    while done != 1:
        stock = raw_input('Enter Stock symbol: ')
        if stock == 'done':
            done = 1

        else:
            price = int(input('Enter Price of Stock: '))
            print("")
            stockNames.append(stock)
            stockPrices.append(price)
        return stockNames, stockPrices

Answer 2

您可能想要raw_input()，因为input()实际上会尝试评估它返回的表达式。
