有本试试下面的代码（要用3.8的Python）

import turtle




t = turtle.Pen()
for x in range(0, 50, 1):
    t.pencolor("#cc66cc")
    t.pensize(2)
    t.circle(x)
    t.left(91)
for x in range(50, 100, 1):
    t.pencolor("#bb00bb")
    t.pensize(2)
    t.circle(x)
    t.left(91)

import time
import random
import turtle
import turtle as T


def Tree(branch, t):

    time.sleep(0.0005)
    if (branch > 3):
        if 8 <= branch <= 12:
            if (random.randint(0, 2) == 0):
                t.color('snow')
            else:
                t.color('lightcoral')
            t.pensize((branch / 3))
        elif (branch < 8):
            if (random.randint(0, 1) == 0):
                t.color('snow')
            else:
                t.color('lightcoral')
            t.pensize((branch / 2))
        else:
            t.color('sienna')
            t.pensize((branch / 10))
        t.forward(branch)
        a = (1.5 * (random.random()))
        t.right((20 * a))
        b = (1.5 * (random.random()))
        Tree(branch - 10 * b, t)
        t.left((40 * a))
        Tree(branch - 10 * b, t)
        t.right((20 * a))
        t.penup()
        t.backward(branch)
        t.pendown()

def Petal(m, t):

    for i in range(m):
        a = (200 - 400 * (random.random()))
        b = (10 - 20 * (random.random()))
        t.penup()
        t.forward(b)
        t.left(90)
        t.forward(a)
        t.pendown()
        t.color('lightcoral')
        t.circle(1)
        t.penup()
        t.backward(a)
        t.right(90)
        t.backward(b)

t = T.Turtle()
w = T.Screen()
t.hideturtle()
t.getscreen().tracer(5, 0)
t.left(90)
t.penup()
t.backward(150)
t.pendown()
t.color('sienna')

Tree(60, t)

Petal(200, t)
