Stopwatch “python”

Well as for this week, we were to create some sort of stopwatch game.
Player gets a point when, they hit “stop” button if it stops on seconds.
A bit even more trickier, but challenge was accepted and completed…Hell Yeah.

# Our mini-project for this week will focus on combining text drawing in
# the canvas with timers to build a simple digital stopwatch that keeps
# track of the time in tenths of a second. The stopwatch should contain
# "Start", "Stop" and "Reset" buttons.
