好的,这个问题很有趣。下面是Python代码实现:
```python
import time
def draw_digit(digit, colon=False):
segments = [[(0, 0), (0, 4)], [(0, 0), (4, 0)], [(0, 4), (4, 4)], [(4, 0), (4, 4)], [(0, 2), (2, 4)], [(2, 4), (4, 2)], [(0, 2), (2, 0)]]
for segment in segments:
x1, y1 = segment[0]
x2, y2 = segment[1]
if digit in [0, 2, 3, 5, 6, 7, 8, 9]:
draw_line(x1, y1, x2, y2)
if digit in [0, 1, 2, 3, 4, 7, 8, 9] and colon and digit != 2:
draw_circle(x=3, y=1)
if digit in [0, 4, 5, 6, 8, 9] and colon and digit != 5:
draw_circle(x=3, y=3)
def draw_line(x1, y1, x2, y2):
# 省略绘制函数的具体实现
pass
def draw_circle(x, y):
# 省略绘制函数的具体实现
pass
while True:
current_time = time.strftime("%H:%M")
clear_screen()
for i, digit in enumerate(current_time):
if digit == ":":
draw_digit(int(digit), colon=True)
else:
draw_digit(int(digit))
if i == 1:
move_cursor(6, 0)
flush()
time.sleep(60)
```
这段代码会每分钟更新一次屏幕上的数字时钟。绘制函数 `draw_digit` 会绘制一个数字的7段数码管,`draw_line` 和 `draw_circle` 分别绘制数码管的线段和圆点。主循环会获取当前时间,然后依次绘制每个数字的数码管,其中第二个数字后面会绘制一个冒号。
