The topic basically tells what I want to to.
I read the documentation, which tells me how to handle signals but not how I can do signalling by myself.
Thanks!

Send the signal signalnum to the thread thread_id, another thread in the same process as the caller. The target thread can be executing any code (Python or not). However, if the target thread is executing the Python interpreter, the Python signal handlers will be executed by the main thread of the main interpreter.
To catch a signal in Python, you need to register the signal you want to listen for and specify what function should be called when that signal is received. This example shows how to catch a SIGINT and exit gracefully.
Use np. abs(input_signal)**2, this gets the absolute value and then the square operator obtains the magnitude.
Python provides the Signal library allowing developers to catch Unix signals and set handlers for asynchronous events. For example, the 'SIGTERM' (Terminate) signal is received when issuing a 'kill' command for a given Unix process.
Directly with the signal package (new in version 3.8). For instance:
import signal
signal.raise_signal( signal.SIGINT )
