Hi,
I'm working on an assignment that requires the user RGB requested
output to create a colour block in fractional steps. I'm pretty much
down to the last bit, however, I've hit a road block in that my
percentages are not showing as a colour block but as the <div> tag
percentages.
Any suggestions on what I'm missing to output the %'s into the colour
block showing colour?
Thanks for any help.

if nsteps > 150:
nsteps = 150
for i in range(0,nsteps-1):
fraction = (i+1.0)/nsteps
r = (1-fraction)*red1 + fraction*red2
g = (1-fraction)*green1 + fraction*green2
b = (1-fraction)*blue1 + fraction*blue2
print '<div class="colourblock" style="background-color: rgb(' +
str(r) + '%,' + str(g) + '%,' + str(b) + '%'"> </div>"
The output of that is (e.g.)
<div class="colourblock" style="background-color: rgb(30%,30%,40%> </div>
Can you see what it is missing?
