これまでの私のコードは次のとおりです。
class Compound(Item):
def __init__(self, itemID, name, products, itemlist):
Item.__init__(self,itemID,name)
self._products = products
self._items_list = itemlist
def get_cost(self):
return self._cost
def get_items_list(self):
return self._items_list
def get_items_str(self):
return "".format(self._itemID, self._name)
def set_items(self, itemlist):
self._itemlist= itemlist
def get_depend(self):
allitems = []
for a in self._set_items:
allitems.append(n[0])
return allitems
def __repr__(self):
return "{0}, {1}, {2}".format(self._itemID, self._name, self._products, self._items_list)
def __str__(self):
return '{0} {1} {2}'.format(self._itemID, self._name, self._products, self._item_list)
class Products():
def __init__(self):
self._products = {}
def get_item(self, itemID):
return self._products.get(itemID)
def add_item(self, itemID, product):
self._products[itemID] = product
def remove_item(self, itemID, product):
if item in products:
self._products.remove(item)
return True
return False
def delete_all(self):
self._products.clear()
def get_keys(self):
return self._products.keys()
def check_depend(self, item):
for i in self._products:
depend = self._products(i).get_depend()
if item in depend:
return True
return False
次のコードを実行すると:
products.add_item('CWH111', Compound('CWH111', 'Mountain Bike Built Wheel', products, [('TR202', 1), ('TU227', 1), ('WH239', 1)]))
products.get_item('CWH111')
私は手に入れたい
CWH111, Mountain Bike Built Wheel, TR202:1,TU227:1,WH239:1
しかし、代わりに、私が得るのは
CWH111, Mountain Bike Built Wheel, <____main____.Products instance at 0x0000000002727588>
私はさまざまなことを試しました。誰かが私が間違っていることを教えてもらえますか?
