python初级turtle画樱花树

好的，我可以回答这个问题。使用Python中的turtle库可以绘制樱花树，下面是一段示例代码：

import turtle
import random

# 设定画布大小和坐标系
canvas = turtle.Screen()
canvas.bgcolor("black")
canvas.setup(800, 600)
canvas.setworldcoordinates(0, 0, 800, 600)

# 定义樱花树的画笔
pen = turtle.Turtle()
pen.speed(0)
pen.hideturtle()

# 定义樱花树的枝干
def tree_branch(length, thickness):
    if length < 10:
        return
    pen.pensize(thickness)
    pen.forward(length)
    angle = random.randint(15, 45)
    pen.right(angle)
    tree_branch(length - random.randint(10, 20), thickness - 1)
    pen.left(angle * 2)
    tree_branch(length - random.randint(10, 20), thickness - 1)
    pen.right(angle)
    pen.backward(length)

# 定义樱花树的花朵
def tree_flower(size):
    petals = random.randint(5, 15)
    angle = 360 / petals
    pen.fillcolor(random.choice(["pink", "lightpink", "hotpink", "deeppink"]))
    pen.begin_fill()
    for i in range(petals):
        pen.forward(size)
        pen.right(angle)
        pen.forward(size)
        pen.right(180 - angle)
    pen.end_fill()

# 绘制樱花树
pen.penup()
pen.goto(400, 0)
pen.pendown()
pen.setheading(90)
pen.left(90 + random.randint(-15, 15))
tree_branch(100, 6)

for i in range(200):
    pen.penup()
    pen.goto(random.randint(0, 800), random.randint(50, 400))
    pen.pendown()
    tree_flower(random.randint(5, 20))

turtle.done()

希望对你有帮助！
