p ython七段数码管

以下是Python实现的七段数码管代码：

# 导入所需模块
import turtle

# 定义数码管的绘制函数
def draw_digit(num):
    # 绘制横线
    if num in [2, 3, 4, 5, 6, 8, 9]:
        turtle.pendown()
    else:
        turtle.penup()
    turtle.fd(40)
    turtle.right(90)
    
    # 绘制左上竖线
    if num in [0, 4, 5, 6, 8, 9]:
        turtle.pendown()
    else:
        turtle.penup()
    turtle.fd(40)
    turtle.right(90)
    
    # 绘制右上竖线
    if num in [0, 2, 6, 8]:
        turtle.pendown()
    else:
        turtle.penup()
    turtle.fd(40)
    turtle.left(90)
    
    # 绘制横线
    if num in [0, 1, 3, 4, 7, 8, 9]:
        turtle.pendown()
    else:
        turtle.penup()
    turtle.fd(40)
    turtle.left(90)
    
    # 绘制右下竖线
    if num in [0, 2, 3, 5, 6, 8, 9]:
        turtle.pendown()
    else:
        turtle.penup()
    turtle.fd(40)
    turtle.left(90)
    
    # 绘制左下竖线
    if num in [0, 2, 6, 8]:
        turtle.pendown()
    else:
        turtle.penup()
    turtle.fd(40)
    turtle.right(90)
    
    # 绘制横线
    if num in [0, 1, 2, 3, 4, 7, 8, 9]:
        turtle.pendown()
    else:
        turtle.penup()
    turtle.fd(40)
    turtle.right(90)
    
    # 返回原点
    turtle.penup()
    turtle.fd(20)
    turtle.right(90)
    turtle.fd(140)
    turtle.left(90)

# 定义主函数
def main():
    # 设置画布大小
    turtle.setup(600, 400)
    # 设置画笔
    turtle.penup()
    turtle.fd(-250)
    turtle.pensize(5)
    
    # 绘制数字
    draw_digit(7)
    draw_digit(0)
    draw_digit(1)
    draw_digit(8)
    draw_digit(6)
    
    # 点击关闭画布
    turtle.exitonclick()

if __name__ == '__main__':
    main()

这段代码使用turtle模块绘制数码管，其中draw_digit(num)函数用于绘制单个数字的七段数码管，main()函数则用于调用draw_digit(num)函数绘制多个数字。
