Please help me with this Python assignment.

The following Python script is missing a class and a function.

def start_my_program(): # define the objects in our Yard Sale items = [ YardSaleItem("tv", 200.00), YardSaleItem("ipod", 25.00), YardSaleItem("speakers", 350.00), YardSaleItem("ottoman", 20.00), YardSaleItem("dresser", 100.00), YardSaleItem("purse", 2000.00), YardSaleItem("jacket", 7.50) ]

print ('Welcome to the garage sale.') print ('This is what I have for sale:') for item in items: item.display_details()

if __name__ == "__main__": start_my_program()

I have tried to write a function YardSaleItem shown as the following. The item in list items can't be displayed.

def YardSaleItem(item, price):

s=" - ";

seq=(item, str(price));

return s.join(seq)
