First program with GUI: Roll a dice

This times is to record a memorable day for me to create a program which look closer to what will be usable in real life.

Code

This program is to act like a 6-face dice, when you press the button, a number will be randomly picked from 1 to 6 and display it

Reflection

I have learned a lot of useful basic syntax and concept in tkinter module. When the interface comes out and it works, I feel like my excitement on learning coding has increase a lot. More confidence to go on the learning path.
