I know it's messy with all those self.soc.* functions, but it works in
one of my current project. I just want to make it more pythonic I also
want to add capability for makeing csv file if I give it input like:
1234,something nice, hey this is something nice
2468,something else, something else

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
