用python写一个艺术签名程序

以下是一个简单的艺术签名程序：

import turtle

# 设置画布和画笔
canvas = turtle.Screen()
canvas.bgcolor("white")
pen = turtle.Turtle()
pen.speed(0)
pen.pensize(3)

# 定义签名函数
def signature():
    # 绘制线条
    pen.penup()
    pen.goto(-100, 0)
    pen.pendown()
    pen.color("red")
    pen.circle(50)
    pen.color("blue")
    pen.circle(40)
    pen.color("green")
    pen.circle(30)
    pen.color("purple")
    pen.circle(20)
    pen.color("orange")
    pen.circle(10)
    pen.color("black")
    pen.circle(5)
    pen.penup()
    pen.goto(50, 0)
    pen.pendown()
    pen.color("red")
    pen.circle(50)
    pen.color("blue")
    pen.circle(40)
    pen.color("green")
    pen.circle(30)
    pen.color("purple")
    pen.circle(20)
    pen.color("orange")
    pen.circle(10)
    pen.color("black")
    pen.circle(5)

# 调用签名函数
signature()

# 隐藏画笔
pen.hideturtle()

# 结束程序
turtle.done()

运行程序后，将会在画布上绘制出两个由彩色圆圈组成的艺术签名。您可以根据自己的喜好和创意来修改签名的样式和颜色。
