非任意对象的集合？ [英] Collections of non-arbitrary objects ?
问题描述
Python似乎有一个方法来记录任意
对象的集合：列表，元组，字典。但是，如果我想要一个非任意对象的集合
怎么办？记录列表，或类似的东西？
Python seems to have a log of ways to do collections of arbitrary
objects: lists, tuples, dictionaries. But what if I want a collection
of non-arbitrary objects? A list of records, or something like that?

将记录编码为对象（类）并将这些对象的实例放在
a中列表或字典（取决于所需的访问权限）。或者，如果你不想做/ b $ b很多记录只是把记录的每个实例（通常是一个记录是
实现为元组至少那个怎么样SQL数据库返回行内的
列表或字典（再次取决于所需的访问权限）。

Code the record as an object (class) and place instances of those objects inside
a list or dictionary (depending on access required). Or if you don''t want to do
much with the records just put each instance of a record (normally a record is
implemented as a tuple at least thats how SQL databases return rows) inside a
list or a dictionary (again depending on access required).

和套装。
And sets.
但如果我想要一个系列怎么办
非任意对象？

然后只将所需的对象类型放入集合中。
Then only put the kind of objects you want in the collection.
记录列表，或类似的东西
A list of records, or something like that
''记录''可以实现为元组，dicts或使用自定义类。
''Records'' can be implemented as tuples, dicts or using a custom class.

然后以非任意方式收集它们。
这是一个轻率的反应，但我不是''理解这个问题。什么
你要求你还没有？列表可以包含已经相同类型的
对象序列。你有什么期望
列表没有提供？

Then collect them in a non-arbitrary way.
That''s a flippant response, but I don''t understand the question. What
are you asking for that you don''t already have? A list can contain a
sequence of objects of the same type already. What are you expecting
that a list does not provide?
