包含列表的字典 [英] dictionary containing a list
问题描述
您好...
我已经设置了一个字典，其中列出了我的列表值。我每次用新值填充我的列表周围和周围的
然后
将此列表转储到字典中。或者我认为...
看起来我倾向于字典值的是
只是指向原始列表的指针，所以之后我所有的迭代都是我的b $ b有一本字典，其每一个值都等于最后一次循环的列表的值:-(
有没有办法实现我的尝试？我做了一些事情
几乎与之前列表中的类相同，在这种情况下是新的
实例是为每个列表条目创建的......
我希望这有一定道理，并且似乎没什么好听的。
简单...
干杯，
Ben
Hello...
I have set up a dictionary into whose values I am putting a list. I
loop around and around filling my list each time with new values, then
dumping this list into the dictionary. Or so I thought...
It would appear that what I am dumping into the dictionary value is
only a pointer to the original list, so after all my iterations all I
have is a dictionary whose every value is equal to that of the list the
final time I looped around :-(
Is there a way to acheive what I was attempting ? I have done something
almost identical with classes in a list before, and in that case a new
instance was created for each list entry...
I hope this makes some sense, and doesn''t seem to head bangingly
simple...
Cheers,
Ben

请考虑您对代码可能做的内容的描述可能不足以诊断。
您可能需要提供：
（1）您的代码清单
（2）少量输入数据
例如[（1，''foo''），（42，''bar''），（1，''zot''）]
（3）您对该输入的期望输出：
例如{1：[''foo''，''zot'']，42：[''bar'']}
干杯，

Please consider the possibility that your description of what you think
your code might be doing is not enough for diagnosis.
You may need to supply:
(1) a listing of your code
(2) a small amount of input data
e.g. [(1, ''foo''), (42, ''bar''), (1, ''zot'')]
(3) the output you expect from that input:
e.g. {1: [''foo'', ''zot''], 42: [''bar'']}
Cheers,

如果你循环...填写[你的]清单，请使用每次新的
列表。您可以使用[]创建一个新的空列表。

Where you "loop around ... filling [your] list", use a new
list every time. You can create a new empty list with "[]".
