好的,可以使用Python的turtle库来模拟七段数码管显示红绿灯,并结合time库来实现倒计时功能。以下是代码实现:
```python
import turtle
import time
# 设置窗口大小和背景色
turtle.setup(400, 400)
turtle.bgcolor('black')
# 定义数码管的各段线段坐标
segments = [
[(0, 60), (-20, 40), (20, 40), (0, 60), (0, 80), (-20, 100), (20, 100), (0, 80)], # a
[(20, 40), (20, 20), (20, 40), (20, 60), (20, 80), (20, 100)], # b
[(-20, 20), (0, 0), (20, 20), (20, 40), (0, 20), (-20, 40)], # c
[(20, 60), (0, 40), (-20, 60), (0, 80), (20, 60)], # d
[(-20, 60), (-20, 40), (0, 40), (20, 40), (20, 60), (0, 80), (-20, 80)], # e
[(0, 80), (-20, 100), (20, 100), (0, 80), (0, 60), (20, 40), (-20, 40)], # f
[(0, 80), (-20, 60), (0, 40), (20, 60), (0, 80), (0, 100), (0, 80)] # g
]
# 定义数字0-9在数码管中的线段编号
digits = [
[0, 1, 2, 4, 5, 6],
[2, 5],
[0, 2, 3, 4, 6],
[0, 2, 3, 5, 6],
[1, 2, 3, 5],
[0, 1, 3, 5, 6],
[0, 1, 3, 4, 5, 6],
[0, 2, 5],
[0, 1, 2, 3, 4, 5, 6],
[0, 1, 2, 3, 5, 6]
]
# 定义红绿灯的数字模式,0表示灭,1表示亮
red_light = [[1, 1, 1, 0, 0, 0, 0], [0, 0, 1, 0, 0, 0, 0], [1, 1, 0, 0, 0, 0, 0]]
green_light = [[0, 0, 0, 0, 1, 1, 1], [0, 0, 0, 0, 0, 1, 0], [0, 0, 0, 0, 1, 1, 0]]
def draw_segment(x, y, on):
"""
绘制一个数码管的线段
:param x: 线段的中心点x坐标
:param y: 线段的中心点y坐标
:param on: 线段是否亮起
"""
turtle.penup()
turtle.goto(x, y)
turtle.pendown()
turtle.color('red' if on else 'darkred')
turtle.begin_fill()
turtle.setheading(0)
for point in segments[i]:
turtle.goto(x + point[0], y + point[1])
turtle.end_fill()
def draw_digit(digit, x, y):
"""
绘制一个数字的数码管
:param digit: 要绘制的数字
:param x: 数码管左上角的x坐标
:param y: 数码管左上角的y坐标
"""
for i in range(7):
if i in digits[digit]:
draw_segment(x + 20 * (i // 3), y - 20 * (i % 3), True)
else:
draw_segment(x + 20 * (i // 3), y - 20 * (i % 3), False)
def draw_light(light, x, y):
"""
绘制红绿灯的数字模式
:param light: 红绿灯的数字模式
:param x: 数码管左上角的x坐标
:param y: 数码管左上角的y坐标
"""
turtle.speed(0)
turtle.hideturtle()
for i in range(3):
for j in range(3):
draw_digit(light[i][j], x + j * 60, y - i * 100)
def countdown(seconds):
"""
倒计时函数
:param seconds: 要倒计时的秒数
"""
for i in range(seconds, 0, -1):
draw_digit(i, -80, -50)
time.sleep(1)
draw_digit(10, -80, -50)
# 绘制红绿灯
while True:
draw_light(red_light, -80, 0)
countdown(30)
draw_light([[0, 0, 0], [0, 0, 0], [1, 1, 0]], -80, 0)
time.sleep(3)
draw_light(green_light, -80, 0)
countdown(30)
draw_light([[0, 0, 0], [1, 1, 0], [0, 0, 0]], -80, 0)
time.sleep(3)
turtle.done()
```
运行代码后,会在窗口中显示一个红绿灯,并且不断循环切换红灯、黄灯和绿灯,每种灯都带有30秒的倒计时。
