newbie question: getting rid of space in string :(

Hello, I'm new to python and I'm writing a very small script which takes each letter of a string and adds text to it (I know this is not a good explanation but you'll understand below :) )

anyway, this is my current code:

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


so when I run let's say textColor("testing","black","red")
it returns:
<black><b>t</b></black> <red><b>e</b></red> <black><b>s</b></black> <red><b>t</b></red> <black><b>i</b></black> <red><b>n</b></red> <black><b>g</b></black>

now this works just fine exept that space in between each block of text, I can't get it to stick together, now I know this is a very easy question but I need some quick help

thanks
