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

| 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)) |
