CMDdice():

A dice rolling simulator for the Windows command-line.

This is an app I made to use on my laptop during Dungeons and Dragons sessions. I normally use real dice but it's nice to have a backup plan and the real point of making this was to practice coding in Python.

^ This is the main screen. Like many terminal based apps selections are made by hitting an indicated key and then enter, or entering text for the list content.

|

^ We will select the number of sides we want our dice to have and how many dice we want to roll.

|

^ The elves in the computer will shake the dice, and...

|

^ ...the results are in! The program prints what each die rolled and the total sum. One shortcoming of this program is that you cant mix dice types in one roll- perhaps that will come in another version.
