It's nice to see you haven't given up. A few suggestions to make you code a
little more creative.

You will be planning to do something else with this right? As it is, you are
looping 250,000 times and resetting the variable rgb each time, losing the
previous value. I imagine that you have other plans.

Oh. I bet this is all supposed to be indented. Nevermind about the above
loop.

Here is what I really meant to look at - yes this commented line
print "RGB(%d, %d, %d)" % (rgb[0], rgb[1], rgb[2])
Since the percent formatter is followed by a tuple (which is what you are
making by putting rgb[0], rgb[1], rgb[2] into parentheses) and rgb is
already a tuple, you can write this much more simply as:
print "RGB(%d, %d, %d)" % rgb
