Joseph,

The comma at the end of the print statment adds a space to the 'string' you 
are printing.  There are several ways to avoid this, perhaps building the 
string up then printing it in one go at the end.. like so:

def textColor(string, color1, color2):
    wholeString=""
    color = color1
    for a in string:
        wholeString=wholeString+"<" +color+ "><b>" +a+ "</b></" +color+ ">"
        if color == color1:
            color = color2
        else:
            color = color1
    print wholeString


as a matter of taste I would use this:-
wholeString=wholeString+"<%s><b>%s</b></%s>" %(color, a, color)
but as I say this is a matter of taste!
