2,638 PointsSortedInventory: super() - issue with task
Hi Guys,
I'm keep getting "Bummer! Hmm, the items don't seem to be sorted" on below task:
"Sorted inventories should be just that: sorted. Right now, we just add an item onto the slots list whenever our add_item method is called. Use the list.sort() method to make sure the slots list gets sorted after an item is added. Only do this in the SortedInventory class."
Well, I'm pretty sure it is sorted, what am I missing?
Thanks, Emil
class Inventory:
def __init__(self):
self.slots = []
def add_item(self, item):
self.slots.append(item)
class SortedInventory(Inventory):
def __init__(self,slots=[]):
super().__init__()
self.slots = slots
def add_item(self, item):
self.slots.append(item)
self.slots.sort()

class Inventory:
def __init__(self):
self.slots = []
def add_item(self, item):
self.slots.append(item)
self.slots.sort();
class SortedInventory(Inventory):
def add_item(self, item):
#super().add_item(item)
self.slots.append(item)
self.slots.sort();

all you need to simply do is call self.slot.sort(). This is using the list inherited by the parent Inventory and just simply adding the function list.sort().
And since you're not calling the super() function here the method stays within the class (here it is class SortedInventory)
The following will suffice:
class Inventory:
def __init__(self):
self.slots = []
def add_item(self, item):
self.slots.append(item)
class SortedInventory(Inventory):
def add_item(self, item):
super().add_item(item)
self.slots.sort()
pass

Python Web Development Techdegree Graduate 18,701 PointsSimla Sophia Yildirim, I just did this exercise, using code that looked like what Tianyang wrote (without the "pass" keyword), I was able to proceed. If your code looks mostly like what's above, but isn't passing, you may just want to check for typos.
