使用turtle库、time库编程实现七段数码管数字时钟

好的,下面是代码实现:
```python
import turtle
import time
# 数字对应的七段编码
digit_to_segment = {
0: [(0, 1), (1, 0), (2, 0), (3, 1), (2, 2), (1, 2), (0, 1)],
1: [(2, 0), (3, 1), (3, 3)],
2: [(0, 1), (1, 0), (1, 2), (2, 2), (3, 1), (3, 3)],
3: [(0, 1), (1, 0), (1, 2), (2, 2), (3, 1), (3, 2), (3, 3)],
4: [(0, 1), (1, 1), (1, 2), (2, 2), (3, 1)],
5: [(0, 0), (0, 1), (1, 2), (2, 2), (3, 1), (3, 2), (3, 3)],
6: [(0, 0), (0, 1), (1, 0), (1, 2), (2, 2), (3, 1), (3, 2), (3, 3)],
7: [(0, 1), (1, 0), (2, 0), (3, 1), (3, 3)],
8: [(0, 0), (0, 1), (1, 0), (1, 2), (2, 2), (3, 1), (3, 2), (3, 3)],
9: [(0, 0), (0, 1), (1, 0), (1, 2), (2, 2), (3, 1), (3, 2), (3, 3)]
}
# 绘制一个数字的七段数码管
def draw_digit(digit, x, y, size):
segments = digit_to_segment[digit]
for segment in segments:
draw_segment(segment[0] * size + x, segment[1] * size + y, size)
# 绘制一个七段数码管的一个段
def draw_segment(x, y, size):
turtle.penup()
turtle.goto(x, y)
turtle.pendown()
turtle.setheading(0)
turtle.forward(size)
turtle.right(90)
turtle.forward(size)
turtle.right(90)
turtle.forward(size)
turtle.right(90)
turtle.forward(size)
# 清空屏幕并绘制时间
def draw_time():
turtle.clear()
now = time.strftime("%H%M%S")
x = -300
y = 0
size = 50
for digit in now:
draw_digit(int(digit), x, y, size)
x += size * 4 / 3
# 初始化窗口和画笔
turtle.setup(800, 600)
turtle.hideturtle()
turtle.speed(0)
turtle.tracer(0, 0)
# 每秒钟更新一次时间
while True:
draw_time()
turtle.update()
time.sleep(1)
```
这个程序会不断地在窗口上绘制当前时间。你可以通过修改 `size` 变量来调整数码管的大小,修改 `turtle.setup()` 来调整窗口大小。
