How to draw a ring of colors using turtle module in python
Question: I have the following code which is supposed to draw a ring of colors around a
circle but only one color if printed and changed 8 times before moving to the
next

    
    
    import turtle
    
    def drawCircle(colorList, radius):
        for color in colorList:
            turtle.color(color)
            for i in range(len(colorList)):
                turtle.penup()
                turtle.setpos(0, -radius)
                xpos=turtle.xcor()
                ypos=turtle.ycor()
                head=turtle.heading()
                turtle.begin_fill()
                turtle.pendown()
                turtle.home()
                turtle.setpos(xpos,ypos)
                turtle.setheading(head)
                turtle.circle(radius)
                turtle.end_fill()
                turtle.penup()
        return
    
    colorList=["#880000","#884400","#888800","#008800",\
            "#008888","#000088","#440088","#880088"]
    
    drawCircle(colorList,200)
    

How would I make it that each arc around the circle is a different color.
[here is an example](http://www.hgtv.com/decorating-basics/color-wheel-
primer/index.html)


Answer: you will need something like this

    
    
    def drawSegment(color,x, y, r, angleStart, angleEnd, step=1):
        #More efficient to work in radians
        radianStart = angleStart*pi / 180
        radianEnd   = angleEnd*pi / 180
        radianStep=step *pi/180
    
        #Draw the segment
        turtle.penup()
        turtle.setpos(x,y)
        turtle.color(color)
        turtle.begin_fill()
        turtle.pendown()
        for theta in arange(radianStart,radianEnd,radianStep):
            turtle.setpos(x + r * cos(theta), y + r * sin(theta))
    
        turtle.setpos(x + r * cos(radianEnd), y + r * sin(radianEnd))
        turtle.setpos(x, y);
        turtle.end_fill()
    
    def drawCircle(colorList,radius):
        #do something to draw an equal segment for each color advancing it around 360 degree's
