great! lines 7 and 8 totally work, though we could definitely use the parent class' constructor instead! It already creates category and condition attributes for us, so let's look at that:
| # super().__init__(category = "Clothing") | |
| ## super().__init__(condition) | |
| self.category = "Clothing" | |
| self.condition = condition | |
| # super().__init__(category = "Clothing", condition) |
and I like that you hardcoded "Clothing" since of course this child class Clothing will always be category "Clothing." No reason to give the user the opportunity to mess that up haha

same as above! we could refactor this a little more to use inheritance more explicitly

so here, we don't actually need to import the literal class Item itself. We aren't instantiating an instance of Item (ie, Item(category="antique",3) ) inside the Vendor anywhere.
There are "items" coming in through parameters, but the class "blueprint" itself can't tell that. On line 7 def add(self, item) the item parameter is simply a placeholder. It could be called banana, apple, and when this method is actually called we could pass an integer, a string, a dictionary, etc. basically, the method itself doesn't know what these parameter values will be.
So unless we are actually creating an instance inside vendor (like our composition examples), we don't need to import it

great job reusing methods you've already made!we can make this even shorter, though:
| self.add(their_item) | |
| friend.add(my_item) | |
| self.remove(my_item) | |
| friend.remove(their_item) | |
| self.add(friend.remove(their_item)) | |
| friend.add(self.remove(my_item)) |
if you recall, the remove method returns the item that is removed, so we can call the remove method right inside the add
