我需要帮助让它问房间的形状，下面列出的房间，他们想要的楼层类型，下面列出，并询问这些有多少房间正在计算。同时打印每个房间的价格，以及所有房间的总价格。运行它的结果低于所有代码。

您当前的代码有两个问题：

1. print (('$'), rooms(room_count) * floor)

这里的floor函数是通过编写floor调用的，而它实际上应该是floor()

2. floor(floorings)

您不需要floorings参数，因为您将该参数作为来自用户的输入。

            raise ValueError('Invalid room shape: ' + equation_type)

    return total_area
room_count = number_of_rooms


print (('$'), rooms(room_count) * floor())

下面是更正后的代码的执行说明

  1. 要求用户输入他想要计算结果的房间数。该值在number_of_rooms变量中读取。

  1. 然后，采购/计算的总成本是通过将flooring的单个成本与所有房间的总成本相加得出的，这是使用rooms(room_shape)函数计算得出的。

  1. rooms(room_shape)函数对所有房间重复一组步骤。步骤是计算每个房间的楼层面积，并将其添加到使用total_area变量跟踪的总楼层面积中。

  1. 根据用户的输入计算出所有房间的总面积后，将返回total_area的值。

  1. 然后将其添加到从floor变量返回的值中。从而为您提供最终成本。

然而，这个地板成本只添加了一次，并且根本不是按照您期望的计算方式计算的。我建议为每个房间计算它，每个房间可能有不同类型的地板，例如

    return total_area
room_count = number_of_rooms


print (('$'), rooms(room_count))

这里唯一的变化是，每个房间都调用floor()，而不是在计算净面积后调用一次。

但是当前的代码仍然存在一个问题，即不能正确使用total和total_count来添加和更新网络区域。相反，要获得单个房间的价格，您可以使用以下方法：
