python - Pylint的R0902是什么意思？为什么我们有这个限制？

Question

R0902限值的背后是什么？太多的实例属性会减慢 python 解释器的速度，还是仅仅是因为太多的实例属性会使类更难理解？

Answer 1

来自(DOCS):

too-many-instance-attributes (R0902):

• Too many instance attributes (%s/%s) Used when class has too many instance attributes, try to reduce this to get a simpler (and so easier to use) class.

然后从 ( Tutorial ):

... but I have run into error messages that left me with no clue about what went wrong, simply because I was unfamiliar with the underlying mechanism of code theory. One error that puzzled my newbie mind was:

:too-many-instance-attributes (R0902): *Too many instance attributes (%s/%s)*

I get it now thanks to Pylint pointing it out to me. If you don’t get that one, pour a fresh cup of coffee and look into it - let your programmer mind grow!

所以，是的，这还不是很清楚。

但是，如上文所述，对于方法、类和模块，越小通常越有利于理解能力、可重用性以及可管理性。当事情变得太大时，通常表明可以重构事情以使其变小。确实没有办法对此设置硬性限制，正如 this question 中所讨论的那样关于如何关闭此消息，pylint 不应该是硬道理。

因此，请将消息作为提示来进一步研究该部分代码。
