用python编写七段数码管绘制

可以使用Python的turtle库来绘制七段数码管。下面是一个简单的示例代码，可以绘制数字8的七段数码管：

import turtle

def draw_line(length, angle):
    turtle.pendown()
    turtle.setheading(angle)
    turtle.forward(length)
    turtle.penup()

def draw_segment(position):
    if position == 1:
        draw_line(40, 0)
    elif position == 2:
        draw_line(40, 45)
    elif position == 3:
        draw_line(40, 90)
    elif position == 4:
        draw_line(40, 135)
    elif position == 5:
        draw_line(40, 180)
    elif position == 6:
        draw_line(40, -135)
    elif position == 7:
        draw_line(40, -90)
    elif position == 8:
        draw_line(40, -45)

def draw_digit(digit):
    if digit in [2, 3, 4, 5, 6, 8, 9]:
        draw_segment(1)
    if digit in [3, 4, 5, 6, 7, 8, 9, 0]:
        draw_segment(2)
    if digit in [2, 3, 5, 6, 8, 9, 0]:
        draw_segment(3)
    if digit in [4, 5, 6, 8, 9, 0]:
        draw_segment(4)
    if digit in [2, 3, 5, 6, 7, 8, 9, 0]:
        draw_segment(5)
    if digit in [2, 6, 8, 0]:
        draw_segment(6)
    if digit in [2, 3, 4, 5, 6, 8, 9, 0]:
        draw_segment(7)

def main():
    turtle.speed(0)
    turtle.penup()
    turtle.goto(-200, 0)
    draw_digit(8)
    turtle.done()

if __name__ == '__main__':
    main()

代码中使用了turtle库的画图函数，通过绘制线段来实现七段数码管的绘制。draw_segment函数用于绘制每个LED灯的线段，draw_digit函数用于根据数字绘制七段数码管。在main函数中，我们设置了画笔的起始位置，并调用draw_digit函数来绘制数字8的七段数码管。
