#100daysofcode :: Python 3.0 , interrupting an endless loop from the keyboard,gracefully

Recently I started out on a mission to further hone my programming skills. Out of the courses that I explored online, the #100daysofcode course from the TalkPython folks appealed to me the most. It is challenging,structured and the instructors are great.

I will be blogging my micro-learnings onthis journey. This is the first one from Day #3

I was in a situation where I had to execute a piece of code and output it’s result on the console until the flow is interrupted by the user (through the console)

Ctrl+C can achieve it .However the interruption was not graceful, it resulted in my Python program “crashing”. So, I had handle this through exception handling.

Here the code that I wrote to handle the keyboard interrupt gracefully

	try:
	start_time = datetime.now()
	#do something endlessly
	while True:
	print(datetime.now())
	time.sleep(1)
	# until interrupted by the keyboard
	except KeyboardInterrupt:
	#behave gracefully in case of interruption
	time_lapsed = (datetime.now() – start_time)
	print('Time elapsed (hh:mm:ss.ms) {}'.format(time_lapsed))
