"""
patterns is a dictionary containing numbers and the numbers normally chosen after them
a is a list of all numbers with chosen numbers appended to it

the computer uses choice to make an informed guess (based on probability)
the computer starts out with only the basic rules
it records the human behaviour

if you type in a repeating pattern of numbers eventually the machine will learn it
