python problem!!

We want to write an inventory program to list some of their quality merchandise! To do this, we want to create a Furniture object. This represents any item at IKEA. Every IKEA product has a base type, an article number, a price, a Swedish-sounding name, a basic description, and optionally, a colour (or blank if there is no colour). Furniture objects should have the ability to store this. Furniture should, of course, be functionally abstract (that is, it would make no sense to instantiate a Furniture object, as it doesn't have all the code needed to make it actually work it is simply a parent class). It needs an accessor and mutator for the price only.

These subcategories should extend (that is, inherit from) Furniture. A Bed also has a length, a width, a footboard height, and a headboard height. These will be expressed in cm. A Nightstand also has width, depth and height, all in cm. An Armchair is their word for a chair, whether it has arms or not. These also have a width, depth, and height, seat width, seat depth, and seat height, all in cm. A Floor Lamp also has a maximum wattage in watts), a height, shade diameter, and cord length. Height and shade diameter are in cm, cord length is in m. You'll note the "also" in each of these. This means that they inherit everything that Furniture has, but they will define more things (behaviours, instance variables) specific to the object in question. You don't have to make accessors and mutators for the subclasses - this will save you time, as the product descriptions are fixed. You will have to make a constructor that can take all these parameters, though. You will need to write a _str_magic method for each object. Read the data from the file ikea.txt - the first item on each row tells you the type of object to be created a single letter), and the rest are parameters as listed above. Have a look at the data file and be sure you understand the format. 1. Read the data, create the specified object, and place it into a list of Furniture. Repeat for each item in the data file. 2. Then, print out each object in the list, and print out the total value of the inventory. The data file will be supplied in this case for you to view. You do NOT need to put that data file anywhere in the Moodle CodeRunner question. It already has it - it's just for your reference. Hints: Furniture should store its data in fully private variables. Furniture should have a _str_method to return its data. Subclasses of Furniture must also take, in their _init_ (constructor methods), the parameters used by Furniture. The first line of a subclass constructor must therefore be super().init(parameters_for_Furniture) where you insert the parameters you're passing to Furniture. The subclasses will also take additional information and store them in their own fully private variables. The subclasses will also have __str_magic methods - these can call on the parent (Furniture) _str_method with super(_str_0 to return part of the String, and save you from having to retype the content generated by the _str_ method of the parent. If you look at similarities between some of the subclasses, you'll quickly realize that, after writing the Armchair class, the Nightstand class could be done very quickly with copy and paste, and some editing. Assume all numbers could have fractional components, including any dimensions, prices, etc. . Do not worry about using dollar signs ($) in the price outputs. Just format them to two decimal places.

Consider this: after reading the line, you can split it into its components, as they are comma delimited. You can then use the components as arguments to a construction call on a new object of the appropriate type
