How to create a analog clock in python ?. Need littlebit of mathematical knowledge.
This is the place you can brush your knowledge in Sin and Cos(Mathemaical functions)
Learn more on “Polar coordinate system” and understand the fundementals.

Clock code has been developed and tested with below versions.

Operating System – Windows 7 64-bit
Python Version – 2.7.11

Packages require – Tkinter
