__del__方法 [英] __del__ methods
问题描述
我有一个课，我需要在它死后做一些最终确定。我知道我可以使用__del__方法，但我似乎记得它
阻止了垃圾收集。是这样的吗？
（请记住，我的代码旨在与python 2.3兼容
python 2.5）
I have a class that I need to do some finalization on when it dies. I
know I can use the __del__ method, but I seem to recall that it
impedes garbage collection. Is this the case?
(keep in mind that my code aims to be compatible with python 2.3 to
python 2.5)

`__del __（）`不是确定性的析构函数。所以忘掉可靠的
自动清理。通过显式调用`close（）`
方法或类似的方法自己动手。

`__del__()` is not a deterministic destructor. So forget about reliable
automatic clean up. Do it yourself with an explicit call to a `close()`
method or something like that.

我不一定需要确定性清理。我打算做
类似于close（）方法。但是我只想让
确保没有任何东西在裂缝之间滑落。 :)
I don''t necessarily need deterministic cleanup. And I plan on doing
something like a close() method as well. But I''d just like to make
sure nothing slips between the cracks. :)

`__del __（）`并不保证*会被调用*，所以不能确定
没有任何东西在裂缝之间滑落。

`__del__()` isn''t guaranteed to be called *at all*, so can''t make sure
nothing slips between the cracks with it.
