python绘制红绿灯图像代码

以下是使用Python绘制红绿灯的代码示例：

import turtle

# 设置画布大小
turtle.setup(500, 500)

# 画圆函数
def draw_circle(color, radius, x, y):
    turtle.penup()
    turtle.goto(x, y)
    turtle.pendown()
    turtle.fillcolor(color)
    turtle.begin_fill()
    turtle.circle(radius)
    turtle.end_fill()

# 画红灯
def draw_red_light():
    draw_circle("red", 50, 0, 0)

# 画黄灯
def draw_yellow_light():
    draw_circle("yellow", 50, 0, -100)

# 画绿灯
def draw_green_light():
    draw_circle("green", 50, 0, -200)

# 画红绿灯框架
def draw_traffic_light():
    turtle.speed(0)
    turtle.hideturtle()
    turtle.pensize(3)
    turtle.penup()
    turtle.goto(-50, 250)
    turtle.pendown()
    turtle.goto(-50, -250)
    turtle.goto(50, -250)
    turtle.goto(50, 250)
    turtle.goto(-50, 250)

# 测试
draw_traffic_light()
draw_red_light()
turtle.done()

你可以在上面的代码中根据需要进行更改，例如修改灯的颜色或位置等。
