python 3.x - How do you add 100 colors using a loop into a turtle graphics design code -
i trying produce color effects gradually change dark light or shift hue assignment, i'm having trouble figuring out how put loop code in rgb color runs 100 different colors.
can give me pointers on how loop through many different colors?
here code have far:
import turtle turtle.setup(width=600, height=500) turtle.bgcolor("blue") turtle.reset() turtle.hideturtle() turtle.speed(0) in range(1000): turtle.forward(i) turtle.right(98) turtle.exitonclick() ps. suppose if can figuring out how colors, should take out "bgcolor".
first, create list containing 1 hundred different colors. each color should rgb tuple, ranging 0 one. there many ways this, typed in favorite colors hand.
colors = [ #reddish colors (1.00, 0.00, 0.00),(1.00, 0.03, 0.00),(1.00, 0.05, 0.00),(1.00, 0.07, 0.00),(1.00, 0.10, 0.00),(1.00, 0.12, 0.00),(1.00, 0.15, 0.00),(1.00, 0.17, 0.00),(1.00, 0.20, 0.00),(1.00, 0.23, 0.00),(1.00, 0.25, 0.00),(1.00, 0.28, 0.00),(1.00, 0.30, 0.00),(1.00, 0.33, 0.00),(1.00, 0.35, 0.00),(1.00, 0.38, 0.00),(1.00, 0.40, 0.00),(1.00, 0.42, 0.00),(1.00, 0.45, 0.00),(1.00, 0.47, 0.00), #orangey colors (1.00, 0.50, 0.00),(1.00, 0.53, 0.00),(1.00, 0.55, 0.00),(1.00, 0.57, 0.00),(1.00, 0.60, 0.00),(1.00, 0.62, 0.00),(1.00, 0.65, 0.00),(1.00, 0.68, 0.00),(1.00, 0.70, 0.00),(1.00, 0.72, 0.00),(1.00, 0.75, 0.00),(1.00, 0.78, 0.00),(1.00, 0.80, 0.00),(1.00, 0.82, 0.00),(1.00, 0.85, 0.00),(1.00, 0.88, 0.00),(1.00, 0.90, 0.00),(1.00, 0.93, 0.00),(1.00, 0.95, 0.00),(1.00, 0.97, 0.00), #yellowy colors (1.00, 1.00, 0.00),(0.95, 1.00, 0.00),(0.90, 1.00, 0.00),(0.85, 1.00, 0.00),(0.80, 1.00, 0.00),(0.75, 1.00, 0.00),(0.70, 1.00, 0.00),(0.65, 1.00, 0.00),(0.60, 1.00, 0.00),(0.55, 1.00, 0.00),(0.50, 1.00, 0.00),(0.45, 1.00, 0.00),(0.40, 1.00, 0.00),(0.35, 1.00, 0.00),(0.30, 1.00, 0.00),(0.25, 1.00, 0.00),(0.20, 1.00, 0.00),(0.15, 1.00, 0.00),(0.10, 1.00, 0.00),(0.05, 1.00, 0.00), #greenish colors (0.00, 1.00, 0.00),(0.00, 0.95, 0.05),(0.00, 0.90, 0.10),(0.00, 0.85, 0.15),(0.00, 0.80, 0.20),(0.00, 0.75, 0.25),(0.00, 0.70, 0.30),(0.00, 0.65, 0.35),(0.00, 0.60, 0.40),(0.00, 0.55, 0.45),(0.00, 0.50, 0.50),(0.00, 0.45, 0.55),(0.00, 0.40, 0.60),(0.00, 0.35, 0.65),(0.00, 0.30, 0.70),(0.00, 0.25, 0.75),(0.00, 0.20, 0.80),(0.00, 0.15, 0.85),(0.00, 0.10, 0.90),(0.00, 0.05, 0.95), #blueish colors (0.00, 0.00, 1.00),(0.05, 0.00, 1.00),(0.10, 0.00, 1.00),(0.15, 0.00, 1.00),(0.20, 0.00, 1.00),(0.25, 0.00, 1.00),(0.30, 0.00, 1.00),(0.35, 0.00, 1.00),(0.40, 0.00, 1.00),(0.45, 0.00, 1.00),(0.50, 0.00, 1.00),(0.55, 0.00, 1.00),(0.60, 0.00, 1.00),(0.65, 0.00, 1.00),(0.70, 0.00, 1.00),(0.75, 0.00, 1.00),(0.80, 0.00, 1.00),(0.85, 0.00, 1.00),(0.90, 0.00, 1.00),(0.95, 0.00, 1.00) ] then, within loop, choose color list. need convert i, goes 0 999, index goes 0 size of list. done dividing ten , converting integer. can set color of turtle using turtle.color.
for in range(1000): idx = int(i/10) color = colors[idx] turtle.color(color) turtle.forward(i) turtle.right(98) the result magnificent rainbow spiral :-)
if not want type in 3 hundred numbers, can lot of vibrant colors moving around upper edge of hsv cylinder. essentially, keep value , saturation constant, , vary hue in each iteration of loop. python's colorsys module convert hsv values rgb.
like before, need change i, varies 0 999, hue value, varies 0 1. time, divide 1000, don't convert integer.
import colorsys #turtle setup stuff goes here in range(1000): color = colorsys.hsv_to_rgb(i/1000, 1.0, 1.0) #compatibility quirk: on 2.7 , below, use i/1000.0 turtle.color(color) turtle.forward(i) turtle.right(98)
