的原因是什麼,當蟒蛇打印的對象,而不是對象本身的地址?
例如輸出打印指令是這樣的:
[< ro.domain.entities.Person object at 0x01E6BA10>, < ro.domain.entities.Person object at 0x01E6B9F0>, < ro.domain.entities.Person object at 0x01E6B7B0>]
我的代碼如下所示:
class PersonRepository:
"""
Stores and manages person information.
"""
def __init__(self):
"""
Initializes the list of persons.
"""
self.__list=[]
def __str__(self):
"""
Returns the string format of the persons list.
"""
s=""
for i in range(0, len(self.__list)):
s=s+str(self.__list[i])+"/n"
return s
def add(self, p):
"""
data: p - person.
Adds a new person, raises ValueError if there is already a person with the given id.
pos: list contains new person.
"""
for q in self.__list:
if q.get_personID()==p.get_personID():
raise ValueError("Person already exists.")
self.__list.append(p)
def get_all(self):
"""
Returns the list containing all persons.
"""
l=str(self.__list)
return l
我有一個Person類爲好,用get_personID()函數。在添加了一些元素並嘗試使用get_all()打印它們之後,它將返回上面的行,而不是我添加的人。
一些代碼將是有益的... – jgr
,什麼是你的打印命令?你是如何獲得這個物體的? –
