Python 使用循环更改二维列表中的多个值

我正在写的程序是在将座位创建为5行5列的二维列表后，在剧院“出售”座位。我已经让它在大多数情况下工作，但如果我选择一个座位旁边的一个已经被标记为出售，我得到的信息，如果这个座位也被出售。 以下是我正在使用的标准：

填充一个5 x 5的网格。然后执行以下操作。创建一个将 继续，直到用户说（是/否）他们想退出，或全部25个席位 都卖了。让用户根据世界其他地区和地区要求座椅位置 列（行，列）-记住列表的位置从0开始， 但用户将要求从行或列位置开始的座位 1.然后，当用户选择座位时，打印出用户的价格，并在价格所在的列表中标记“SS”（已售出座位）。然后 打印出所有座位，以便用户可以选择其他座位。下次什么时候 循环中的用户要求一个座位，确保您检查并查看是否有 座位已售出（表中有一个“SS”）。如果售出，请告知 用户–否则返回价格并标记座位已售出。之后 用户要求退出或所有座位售出，或循环结束， 然后打印出如下所示的列表-显示售出的座位（SS） 和未售出的座位（未售出的座位仍有价格）

这是我的代码：

def main():
seatList = [
    [50,50,50,50,50],
    [40,45,45,45,40],
    [30,35,35,35,30],
    [20,20,20,20,20],
    [10,10,10,10,10],
]
cont = "y"
while cont.lower() == "y":
    print("Here is the seating arrangement:")
    availableSeat = seatPrinter(seatList)
    totalRow = int(len(seatList)) - 1
    totalColumn = int(len(seatList[0])) - 1
    seatRow = int(input("Please enter a row number (1 to %d):"%totalRow))
    seatColumn = int(input("Please enter a seat number (1 to %d):"%totalColumn))
    seatStatus = seatAvailable(seatList, seatRow, seatColumn)
    cont = input("Would you like to reserve another seat?(Y/N)")

def seatPrinter(seats):
    for i in range(len(seats[0])):
        print(seats[i])

def seatAvailable(seats, row, column):
    for i in range(len(seats)):
        for j in range(len(seats)):
            if seats[i][j] is not 'SS':
                seats[i][j] = 'SS'
                print("Your seat is in row %d seat number %d"%(i+1, j+1))
                return
            else:
                print("Sorry, that seat isn't available.")
                return

main()

现在，这是我得到的输出：

Here is the seating arrangement:
[50, 50, 50, 50, 50]
[40, 45, 45, 45, 40]
[30, 35, 35, 35, 30]
[20, 20, 20, 20, 20]
[10, 10, 10, 10, 10]
Please enter a row number (1 to 4):1
Please enter a seat number (1 to 4):1

Here is the seating arrangement:

[40, 45, 45, 45, 40]

[20, 20, 20, 20, 20]
[10, 10, 10, 10, 10]
Please enter a row number (1 to 4):1
Please enter a seat number (1 to 4):2
Sorry, that seat isn't available.

我似乎不明白为什么我不能在同一排预定更多的座位，谢谢你的帮助

def main():
    seatList = [
        [50,50,50,50,50],
        [40,45,45,45,40],
        [30,35,35,35,30],
        [20,20,20,20,20],
        [10,10,10,10,10],
    ]
    cont = "y"
    while cont.lower() == "y":
        print("Here is the seating arrangement:")
        availableSeat = seatPrinter(seatList)
        totalRow = int(len(seatList)) - 1
        totalColumn = int(len(seatList[0])) - 1
        seatRow = int(input("Please enter a row number (1 to %d):"%totalRow))
        seatColumn = int(input("Please enter a seat number (1 to %d):"%totalColumn))
        seatStatus = seatAvailable(seatList, seatRow, seatColumn)
        cont = input("Would you like to reserve another seat?(Y/N)")

def seatPrinter(seats):
    for i in range(len(seats[0])):
        print(seats[i])

def seatAvailable(seats, row, column):
    if seats[row-1][column-1] is not 'SS':
        seats[row-1][column-1] = 'SS'
        print("Your seat is in row %d seat number %d"%(row,column))
        return
    else:
        print("Sorry, that seat isn't available.")
        return

main()

结果,

您不必使用for循环来检查座位的可用性，只需使用索引行和列/。啊，这太好了！谢谢在重读这篇文章之后，我也意识到，如果所有座位都卖完了，我还没有在部分中添加关于停车的内容。
