如何将列表传递给__init__值/定义？ [英] How do I pass a list to a __init__ value/definition?
问题描述
让我先从我的免责声明开始，说我是新来的电脑
编程并在过去三周内完成了这项工作。我可能不会用所有的行话来完全正确，所以请耐心等待。
无论如何，我正在编写一个有类的函数名为
MultipleRegression。我希望__init__
方法下的一个变量成为一个列表。我有：
class MultipleRegression：
def __init __（self，dbh，regressors，fund）：
self .dbh = dbh
self.regressors = regressors
我希望能够输入回归量列表如
MultipleRegression（dbh，[1,2,3,4]，5）。但是当我这样做时，只有1
被传递给回归量，从而传递给self.regressors。有没有
简单的方法来解决这个问题？请记住，列表的长度可能会有所不同，所以我不能只创建一组变量，然后将它们混合成一个列表。
非常感谢！我真的很喜欢这个编程的东西。
它真正具有挑战性，对我的工作非常有用。

真的吗？
class MultipleRegression：
def __init __（self，dbh，regressors，基金）：
self.dbh = dbh
self.regressors = regressors
foo = MultipleRegression（42，[1,2,3， 4]，5）
打印foo.regressors
打印[1,2,3,4]
试一试，看看。

你的问题出在其他地方，因为当我这样做时，我得到了
正确的结果：
>> mr = MultipleRegression（10，[1,2,3,4]，5）
print mr.regressors
[1,2,3,4]
所以我想的方式你把你的清单传给MultipleRegression是
也许是错的。我希望你的问题是在
中从未知数量的项目中创建该列表。基本上你需要
创建列表，重复添加必要的项目，直到你完成
，然后将它传递给MultipleRegression。如何创建和
填充该列表将取决于您从何处获取数据。

你的工作对我来说很好：
Python 2.4.1（＃2，2005年3月31日，00： 05:10）
[GCC 3.3 20030304（Apple Computer，Inc。build 1666）]在darwin上
输入help，copyright，credit ;或许可证或欲获得更多信息。
>> class MultipleRegression：
.... def __init __（self，dbh，regressors，fund）：
.... self.dbh = dbh
.... self.regressors = regressors
....
>> spam = MultipleRegression（''dbh''，[1,2,3,4]，5）
spam.regressors
[1,2,3,4]
是什么让你认为你只有列表的第一个成员？可以
你告诉我们那些'不工作的代码吗？

Let me start with my disclaimer by saying I''m new to computer
programming and have doing it for the past three weeks. I may not be
completely correct with all the jargon, so please bear with me.
Anyways, I''m writing a function which has a class called
"MultipleRegression." I want one of the variables under the __init__
method to be a list. I''ve got:
class MultipleRegression:
def __init__(self, dbh, regressors, fund):
self.dbh = dbh
self.regressors = regressors
and I want to be able to enter regressors as a list like
MultipleRegression(dbh, [1,2,3,4], 5). But when I do this only the 1
gets passed to regressors and thus to self.regressors. Is there any
simple way to fix this? Keep in mind that the length of the list may
vary, so I can''t just create a set number of variables and then mash
them together into a list.
Thanks so much! I really am getting into this whole programming thing.
Its real challenging and very useful for my work.

self.regressors = regressors
foo = MultipleRegression(42, [1,2,3,4], 5)
print foo.regressors
prints [1,2,3,4]
Try it and see.

correct results:
>>mr = MultipleRegression(10, [1,2,3,4], 5)
print mr.regressors
[1, 2, 3, 4]
So I think the way you are passing your list to MultipleRegression is
perhaps wrong. I expect your problem is in creating that list in the
first place from an unknown number of items. Basically you need to
create the list, repeatedly add the necessary items to it until you''re
done, and then pass that to MultipleRegression. How to create and
populate that list will depend on where you''re getting the data from.

[GCC 3.3 20030304 (Apple Computer, Inc. build 1666)] on darwin
Type "help", "copyright", "credits" or "license" for more information.>>class MultipleRegression:
.... def __init__(self, dbh, regressors, fund):
.... self.dbh = dbh
.... self.regressors = regressors
....>>spam = MultipleRegression(''dbh'', [1,2,3,4], 5)
spam.regressors
[1, 2, 3, 4]
What makes you think you only have the first member of the list? Can
you show us the code that''s not working?
