This is a small project I've started since beginning to learn Python. So far I'd describe it as a terminal companion named beta, he knows a few simple commands and even has a battle feature! I'm planning to keep learning more Python whilst making edits and adding additional features.

beta.py

#define beta
#hi I\'m beta! Your personal terminal companion!
#
#beta has a few handfuls of commands with responses
#he is also currently programmed with three mini-games!
#all coded from scratch, by me, in Python learned from codecademy.com - James Litewski
#also programmed in are personal reminders for the programmer,
#these are able to be randomly called by the "Remind me again.." command
#now that I think of it, maybe I'll add in a way to add new reminders later! :D
#current known commands:
#What are you?
#Who are you?
#Who is James?
#define personality
#Fight me! '''mini-game!'''
#Boom goes the dynamite!
#Where are you from?
#Would you like a coffee?
#Do you like cats?
#Remind me again..
#Highroll Castle! '''another mini-game!'''
#Let's play a game! '''a third mini-game!'''
#What is your purpose?
#End
#
#over the course of running, currently beta creates a few data files..
#username.txt '''this stores your name!'''
#fights.txt '''this counts your number of fights and changes the responses accordingly'''
#betastats.txt '''this records beta's stats for use in Fight me!'''
#userstats.txt '''same thing but for the user'''
