September 2, 2022 - The Python Signal Library allows us to interact with OS level signals for asynchronous events and handle them with custom Signal Handlers. For example, if we press CTRL + C during a programs execution, this terminates the programs execution.

August 6, 2022 - For all common operating systems, there is a standard pattern for assigning these signals, which are generally short for integers. In Python, these signals are defined in the signal module.

Signals are identified by integers and are defined in the operating system C headers. Python exposes the signals appropriate for the platform as symbols in the signal module. For the examples below, I will use SIGINT and SIGUSR1.

June 16, 2019 - A handler for a particular signal, once set, remains installed until it is explicitly reset (Python emulates the BSD style interface regardless of the underlying implementation), with the exception of the handler for SIGCHLD, which follows the underlying implementation.
