timers

A collection of countdown timers, written in Python

clitimer.py - A command line countdown timer

clitimer.py takes a single argument - the start time to count down from - shows a countdown and rings the system bell when finished. Usage below:

python clitimer.py 60
# or
python clitimer.py 1:00

Requirements

As the script uses the \a notation to ring the system bell, this script won't work on the windows command line.

browsertimer.py - Using bokeh to produce a countdown timer

browsertimer.py uses JavaScript callbacks with bokeh.plotting to create an HTML timer that counts down from a user-defined time to zero.

python browsertimer.py

When the timer launches in the browser, you can use the sliders to adjust the limit on the timer, and the buttons to start, stop/pause, and reset the timer.

Requirements

• bokeh 0.12 or above
