python - Python，错误/错误，两次打印输出，定义/函数

Question

[更新] 我看到 roomidea() 在两个不同的位置被调用：

def price(): sBedsize, sRoomview, sVehicle, iRoomnum, iNights = roomidea() 和 sBedsize, sRoomview, sVehicle, iRoomnum, iNights = roomidea()

但问题是，每当我删除 def price(): 下的一个位置时，它都会导致错误说 iNights 未定义它定义的但仅在第一个 def 下。

我目前的问题是，每当我在 pycharm 中运行我的程序时，它都会打印两次输入，现在我对为什么会发生这种情况有了一些想法，但是每当我尝试解决这些想法时，它要么不起作用，要么导致更多错误或问题。现在我在一个函数中输入了我的输入，稍后我会回调该函数，现在我不知道我是否会回调它两次，因为我的第二个 def 中也有回调，这是价格之一，但如果你看着告诉我。

import time
def roomidea():
    sBedsize = input("For your room do you want a queen-size bed or a king-size bed? Type Queen for queen-size or King for king-size:\t")
    sRoomview = input("For your room do you want the standard view or the atrium view? Type Standard for standard-view or Atrium for atrium-view:\t")
    sVehicle = input("Will you be parking at our hotel? Type Yes if you are, or No if you are not:\t")
    iRoomnum = int(input("Please enter the amount of rooms you wish to check out:\t"))
    iNights = int(input("Please enter the amount of nights you wish to stay:\t"))
    return sBedsize, sRoomview, sVehicle, iRoomnum, iNights

您可能需要考虑更好的逻辑。问题是，由于您在方法sBedSize, sRoomview, sVehicle之外使用def price():，因此预计会崩溃。把它们从price()

return sBedsize, sRoomview, sVehicle, iRoomnum, iNights, dPrice1, dPrice2, dPrice3, dPrice4, dPrice5, dResortfee1, dResortfee2, dTotalqs, dTotalqa, dTotalqsv, dTotalqav, dTotalks, dTotalka, dTotalksv, dTotalkav, dTaxqs, dTaxqa, dTaxqsv, dTaxqav, dTaxks, dTaxka, dTaxksv, dTaxkav, dOverallqs, dOverallqa, dOverallqsv, dOverallqav, dOverallks, dOverallka, dOverallksv, dOverallkav

sBedsize, sRoomview, sVehicle, iRoomnum, iNights, dPrice1, dPrice2, dPrice3, dPrice4, dPrice5, dResortfee1, dResortfee2, dTotalqs, dTotalqa, dTotalqsv, dTotalqav, dTotalks, dTotalka, dTotalksv, dTotalkav, dTaxqs, dTaxqa, dTaxqsv, dTaxqav, dTaxks, dTaxka, dTaxksv, dTaxkav, dOverallqs, dOverallqa, dOverallqsv, dOverallqav, dOverallks, dOverallka, dOverallksv, dOverallkav = price()

#sBedsize, sRoomview, sVehicle, iRoomnum, iNights = roomidea()
