python信号处理教程

Welcome to python signal processing tutorial. This is going to be a very basic lesson on how to handle signals with python. A computer receives and transmits various commands with the help of signals. An operating system has got at least one signal listed for each type of command it is programmed to receive or generate. And now, we will look at the basic signal processing in python 3.

欢迎使用python信号处理教程。 这将是关于如何使用python处理信号的非常基础的课程。 计算机借助信号来接收和发送各种命令。 操作系统针对其编程要接收或生成的每种命令列出了至少一个信号。 现在，我们将介绍python 3中的基本信号处理。

什么是信号 (What is Signal)

A signal is like a notification of an event. When an event occurs in the system, a signal is generated to notify other programs about the event. For example, if you press Ctrl + c, a signal called SIGINT is generated and any program can actually be aware of that incident by simply reading that signal. Signals are identified by integers.

信号就像事件的通知。 当系统中发生事件时，会生成一个信号以通知其他程序有关该事件的信息。 例如，如果您按Ctrl + c ，则会生成一个称为SIGINT的信号，并且任何程序实际上都可以通过简单地读取该信号来了解该事件。 信号由整数标识。
