下面是一个简单的 Python 海龟绘图画树的示例代码,你可以根据自己的需要进行修改和优化。
```python
import turtle
def draw_tree(branch_len, t):
if branch_len > 5:
t.forward(branch_len)
t.right(20)
draw_tree(branch_len - 15, t)
t.left(40)
draw_tree(branch_len - 15, t)
t.right(20)
t.backward(branch_len)
def main():
t = turtle.Turtle()
screen = t.getscreen()
t.left(90)
t.up()
t.backward(200)
t.down()
t.color("green")
draw_tree(100, t)
screen.exitonclick()
if __name__ == "__main__":
main()
```
运行后,会弹出一个窗口,显示画出的树。你可以根据需要修改代码中的参数来调整树的形状和大小。

pen.goto(0, 100)
pen.pendown()
pen.begin_fill()
pen.circle(20)
pen.end_fill()
# 绘制星星
pen.color("yellow")
pen.penup()
pen.goto(-10, 150)
pen.pendown()
pen.begin_fill()
for _ in range(5):
pen.forward(30)
pen.right(144)
pen.end_fill()
# 结束绘制
pen.hideturtle()
canvas.exitonclick()
```
python海龟绘图画长条形的树
可以使用Python的turtle模块来绘制长条形的树,代码如下:
```python
import turtle
def draw_tree(length):
if length > 5:
turtle.forward(length)
turtle.right(25)
draw_tree(length - 15)
turtle.left(50)
draw_tree(length - 15)
turtle.right(25)
turtle.backward(length)
turtle.speed('fastest')
turtle.left(90)
turtle.penup()
turtle.backward(200)
turtle.pendown()
turtle.color('brown')
draw_tree(100)
turtle.done()
```
运行该代码,会得到如下图所示的长条形的树:
