我发现大多数程序都是很自然地创建和处理对象的，所以我通常不会担心它。
一些例子：
person = Person('john')
person = Person('james')
# Whoops! 'john' has died!
people = []
people.append(Person('john'))
# ...
# All 'Persons' live in people
people = []
# Now all 'Persons' are dead (including the list that referenced them)
class House():
def setOwner(self, person):
self.owner = person
house.setOwner(people[0])
# Now a House refers to a Person
people = []
# Now all 'Persons' are dead, except the one that house.owner refers to.
我认为您所追求的是：
people = {}
people['john'] = Person('john')
def removePerson(personName):
del people[personName]
removePerson('john')
在这种情况下，people是主列表，您可以控制何时Person从列表（它的字典）中添加和删除列表。
您可能必须仔细考虑一个被创建的人的概念，然后彻底死去：一旦创建，这个人将如何与模拟互动。死亡后，如何解开引用？（一个人可以引用其他内容，例如House在我的示例中可以使一个人存活）。您可以让其他对象仅保留该人的名字。
