Hello All,
I have this class that I use in one of my projects. I know it's missing
functionality and some things could have been done differently. Can you ehlp
me make this class better? What can I do to make it more resistant to error?
You can find the stdout_colours class on Google if you want it, JFGI I want
to make it more pythonic. I come from a PHP background, can you tell?
Any and all help is appreciated
-Alex
