试图以面向对象的方式传递类和函数中的变量列表

Question

我试图以面向对象的方式在Class和Function中传递变量列表但面临一些错误,我不明白它有什么问题我在Eclipse中使用PyDev

码

class Mydetails:
    __details = ''

    def __init__(self,details):     # constructor
        #self.__details['country'] = details['country']
        self.__details = details

    def set_element(self,details):
        self.__details = details

    def get_list(self,details):
        return self.__details

details = ['ABC','DEF','GHI','JKL']
pdetails = Mydetails()
pdetails.set_element(details)
print(pdetails.get_list())

OUTPUT

Traceback (most recent call last):
  File "C:\workspace\python\pythonapp\list.py", line 18, in <module>
    pdetails = Mydetails()
TypeError: __init__() missing 1 required positional argument: 'details'

Answer 1

在这一行:

def __init__(self,details):  

你使init函数取一个参数(细节),但在这里:

pdetails = Mydetails()  

你不给它一个参数!你可能想做的是:

pdetails = Mydetails(details)

在旁注上你的def get_list(self,details):功能没有意义,你为什么要传递一个不被使用的参数？
