有没有办法在Python3.8中使用rgb颜色？

我试图指定RGB颜色以使程序生成随机颜色。我正在尝试如何做RGB颜色，但是会显示一个错误，指出它输入的颜色不好，更具体地说，是“ raise TurtleGraphicsError（“坏的颜色序列：％s”％str（color））turtle.TurtleGraphicsError：坏的颜色序列：（0，255，0）“

from random import randint

myPen = turtle.Turtle()
myPen.ht()
myPen.speed(0)
myPen.pencolor(0,255,0)
myPen.begin_fill()
points = [[-500,-400],[0,500],[500,-400]] #size of triangle
def getMid(p1,p2):
    return ( (p1[0]+p2[0]) / 2, (p1[1] + p2[1]) / 2) #find midpoint

def triangle(points,depth):

    myPen.up()
    myPen.goto(points[0][0],points[0][1])
    myPen.down()
    myPen.goto(points[1][0],points[1][1])
    myPen.goto(points[2][0],points[2][1])
    myPen.goto(points[0][0],points[0][1])

    if depth>0:
        z=(randint(0,255),randint(0,255),randint(0,255))
        myPen.fillcolor(z)
        triangle([points[0],
                        getMid(points[0], points[1]),
                        getMid(points[0], points[2])],
                   depth-1)
        triangle([points[1],
                        getMid(points[0], points[1]),
                        getMid(points[1], points[2])],
                   depth-1)
        triangle([points[2],
                         getMid(points[2], points[1]),
                         getMid(points[0], points[2])],
                   depth-1)



triangle(points,7)
