Watch Python Signal Handler Video Tutorials & Courses

I this video we dive into managing signals in Python and ensuring that we are able to handle OS signals robustly and with consideration to what the script was doing. Running Python 3.8 on Ubuntu 18.04 we show that signals sent to the script make cause the script to crash but when we interrupt or trap the signal we can deal with the event more carefully #!/usr/bin/env python3 import signal from time import sleep import mysql.connector #sudo apt install python3-mysql.connector config = { 'user':'dbuser', 'password': 'Password1', 'host': '127.0.0.1' } cnx = mysql.connector.connect(**config) #valid_signals = signal.valid_signals() def exit_handler(signum, frame): print() print("close db...") if cnx.is_connected(): cnx.close() print("exiting....") exit(0) signal.signal(signal.SIGINT, exit_handler) while 1: print("Press Ctrl + C") sleep(3) Additionally you can find my video courses on Pluralsight: http://pluralsight.com/training/Authors/Details/andrew-mallett and take time to see my own site http://www.theurbanpenguin.com -~-~~-~~~-~~-~- Please watch: "RHCSA 9 Working With Podman Containers" https://www.youtube.com/watch?v=piwcpd_hWn0 -~-~~-~~~-~~-~- Key Highlights & Overview: Mastering <strong>Python Signal Handler</strong> is essential for modern technical workflows and software skills.
