Create digital_clock.py

Mohitkumar6122 · web-flow · commit 50aaae42bfaa · 2020-08-12T23:06:17.000+05:30
This short Python code gets the local time from the PC as a formatted string using time.strftime('%H:%M:%S'). The time string is displayed in a label using a larger font. A recursive function checks the time five times per second, and updates the time string, if it has changed. Five times per second may sound like overkill, but keeps the display from acting spasmodic.
