本文提供了一系列使用Python的Turtle模块绘制各种图形的代码示例，包括太阳花、五角星、彩色螺旋线、方形蜘蛛网等，适合初学者实践和学习。

太阳花

1	# coding=utf-8
2	import turtle
3	import time
4
5	# 同时设置pencolor="red", fillcolor="yellow"
6	turtle.color("red", "yellow")
7
8	# 开始填充
9	turtle.begin_fill()
10	for _ in range(50): # 循环50次, 从0到49
11	turtle.forward(200) # 前行200
12	turtle.left(170) # 左转170°
13	# 结束填充
14	turtle.end_fill()
15
16	# 不会退出, 而是等待
17	turtle.mainloop()

五角星

# coding=utf-8
import turtle
import time

turtle.pensize(5)          # 线宽
turtle.pencolor("yellow")  # 线的眼神
turtle.fillcolor("red")    # 填充颜色

def draw_5AnglesShape():
    turtle.begin_fill()
    for _ in range(5):
        turtle.forward(200)
        turtle.right(144)
    turtle.end_fill()
    time.sleep(2)

def draw_word():           # 写文字
    turtle.penup()
    turtle.goto(-150, -120)
    turtle.color("violet")
    turtle.write("五角星绘制完毕", font=('Arial', 40, 'normal'))

if __name__ == "__main__":
    draw_5AnglesShape()

13	turtle.forward(2*x)
14	turtle.color(colors[x % 4])
15	turtle.left(91)
16	#turtle.tracer(True)
