The above code is very easy to understand when looking at it, but from what 
I see of other programmers this would not be as pythonic.

In the above function please let me know if I am correct in my 
The first line of course would be the defining of the function and puting 
something in the parenthesis indicates that you will be passing a value to 
this function.
The second line says that for each string in the colorPrint statement check 
to see what the color code is.
The third line says that if it detects a ",#" to change it to a color based 
on the textcolor function in the WConio module.
The fourth line puzzles me though.  I think it says that when the textcolor 
returns the zero that it doesn't print the None?  I am not sure though.

Could you let me know if I have the right idea?

Thanks in advance,
