可以python做一些内核的东西吗？ [英] can python do some kernel stuff?
问题描述
大家好吧
python现在已经发展成为一种多功能的语言，可以为许多不同的目的完成任务。然而，
AFAIK，对它的内核编码能力知之甚少。
所以我想知道python是否可以做一些内核编码
曾经是C / C ++的私人花园。例如，python
拦截系统级别的键盘输入？有人告诉我
这是内核的事情，不是吗？
Hi to all
python now has grown to a versatile language that can
accomplish tasks for many different purposes. However,
AFAIK, little is known about its ability of kernel coding.
So I am wondering if python can do some kernel coding that
used to be the private garden of C/C++. For example, can python
intercept the input of keyboard on a system level? someone told me
it''s a kernel thing, isn''t it?
推荐答案

好吧，直截了当地说，我怎么知道在系统上按下一个键 -
等级如果
使用python？
well, straightly speaking, how can I know a key is pressed on a system-
level if
using python?

内核编程有什么用途？你可以用例如pygame来
获得击键。或者在linux下，读取（如果你是root用户）键盘
输入文件 - 我这样做是为了支持连接到
机器的几个键盘。
原来的问题：不，python不能用作内核
编程语言。除了其他原因外，性能& GIL
可以防止这种情况发生。

What has that todo with kernel programming? You can use e.g. pygame to
get keystrokes. Or under linux, read (if you are root) the keyboard
input file - I''ve done that to support several keyboards attached to a
machine.
And the original question: no, python can''t be used as kernel
programming language. Amongst other reasons, performance & the GIL
prevent that.
