Python 3.x Python3.4程序应该在类中使用______;槽吗？

类的

\uuuuuuuuuuuuuuuuuuuuuuuuuuuu

属性是用Python 2或更早版本创建的，根据回答的注释，Python 3.3似乎已经改进了，因此内存大小的优势可能不是在例如Python 3.4程序中使用

\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

那么，我应该清理我的代码并删除类中使用的
\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu
吗？或者，即使在Python 3.4程序中使用
\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu。这是为了在可能有成千上万个实例的情况下节省内存。这就是在Python2中使用它们的原因，也是在Python3中使用它们的原因。
首先为什么要使用
\uuuuuuuuuuuuuuuu
？您的应用程序是否遇到内存问题？内存分析器能告诉你关于你的程序在有和没有
\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu
的情况下运行的什么？我提前添加了
\uuuuuuuuuuuuuuuuuuuu。然而，使用
\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu。除非您需要，否则使用
\uuuuuuu slots\uuuuuuu
不是一个好主意（将其视为一种可以工作但容易中断的优化黑客）。您所说的“It break instance compare”是什么意思？@EthanFurman：可以使用
\uuu dict\uuuuuuuuuu
进行一般的相等性检查，如下所示，如果使用
\uuuuuuuuuuuuuuuuuuuuuuuuuuuu
没有
\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu。
