First of all, I am writing a code to print inventory of Ikea from a file that has lines like this, F,301.841.73,9.99,HOLMÖ,Floor lamp – gives a soft mood light,none,75,116,22,2.2
where the third one “9.99” is the price of that furniture item. i have getter and setter for the price variable as well.
def setPrice(self, f_price): self.__price = f_price def getPrice(self): return self.__price
there is main class called Furniture and other sub-classes for items like “BED”, “NIGHTSTAND”, “ARMCHAIR” etc..
there is a UNIT test framework for these classes. where it creates a list, them opens the file and using loop , it adds all the variables for furniture item like type, an article number, a price, a Swedish-sounding name, a basic description, and optionally, a colour from Furniture class as well as sub variables from sub class to list.
then, AT last, we need to count Total value of inventory. where I initialized a Total_value variable to 0.
total_value = 0 for furniture_item in inventory: print(str(furniture_item)) # print the item print("="*30) # print a separator # ADD THE PRICE OF THE ITEM TO THE ACCUMULATOR VARIABLE total_value += (value)
when I try to get price from getPrice function:
price = Furniture.getPrice total_value += price
it gives me error like this:
*****Error*** Traceback (most recent call last): File "__tester__.python3", line 212, in <module> total_value += price TypeError: unsupported operand type(s) for +=: 'int' and 'function'**
when i do like this:
Furniture.getPrice = price total_value += price
It gives me the value of
**Total Inventory Value: 3184.0**. But, the value expected is
**Total Inventory Value: 1432.91**, I don’t know what wrong I am doing.
If anyone can suggest to me how to get this expected value, that would be great!!!
I’m guessing you want
total_price += furniture_item.getPrice()
