我无法使用此功能。它的目的是从列表中删除项目。
def sell(inventory_list):
print()
count = int(input('How many items would you like to sell? '))
print()
for count in range(count):
print()
type = input('Enter the type of item you wish to sell? ')
print()
name = input('Enter the name of the item you wish to sell? ')
print()
price = float(input('What is the price of the item you wish to sell? $'))
items = Plant.SubPlant(type, name, price)
inventory_list.remove(items)
return inventory_list

您的广告资源列表中没有您要删除的新实例。仅仅因为它包含相同的atrrs /值并不意味着它们是相同的。
为了能够这样做,可能在SubPlant类中实现方法__eq__
:
class SubPlant(object):
def __init__(self, type, name, price):
self.type = type
self.name = name
self.price = price
def __eq__(self, other):
return self.__dict__ == other.__dict__
