好的,以下是使用Python中的turtle和time库编写七段数码管式学号滚动的代码示例:
```python
import turtle
import time
# 定义七种数字的七段显示
segments = [
[(0, 50), (50, 50), (50, 100), (0, 100), (0, 50)], # 0
[(0, 0), (0, 50), (50, 50), (50, 0), (50, 100), (0, 100)], # 1
[(0, 0), (50, 0), (50, 50), (0, 50), (0, 100), (50, 100)], # 2
[(0, 0), (50, 0), (50, 50), (0, 50), (50, 50), (50, 100), (0, 100)], # 3
[(0, 0), (0, 50), (50, 50), (50, 0), (50, 100)], # 4
[(50, 0), (0, 0), (0, 50), (50, 50), (50, 100), (0, 100)], # 5
[(50, 0), (0, 0), (0, 100), (50, 100), (50, 50), (0, 50)], # 6
[(0, 0), (50, 0), (50, 100), (0, 100)], # 7
[(0, 0), (0, 100), (50, 100), (50, 50), (0, 50), (50, 50), (50, 0)], # 8
[(0, 0), (0, 50), (50, 50), (50, 0), (50, 100), (0, 100)], # 9
]
# 定义每个数字的宽度和高度
digit_size = (60, 100)
# 定义滚动窗口的宽度
window_width = 400
# 定义学号
student_id = "20210001"
# 创建画布和海龟对象
canvas = turtle.Screen()
canvas.bgcolor("black")
turtle = turtle.Turtle()
turtle.hideturtle()
turtle.speed(0)
turtle.penup()
# 定义滚动窗口的起始位置
window_x = window_width / 2
# 无限循环滚动
while True:
# 清空画布
turtle.clear()
# 计算当前数字的总宽度
total_width = len(student_id) * digit_size[0]
# 计算第一个数字的起始位置
x = window_x - total_width
# 画出所有数字
for digit in student_id:
# 画出当前数字的七段显示
for segment in segments[int(digit)]:
turtle.goto(x + segment[0], segment[1])
turtle.pendown()
turtle.penup()
x += digit_size[0]
# 更新窗口
canvas.update()
# 等待一段时间
time.sleep(0.1)
# 移动滚动窗口
window_x -= 5
# 如果滚动窗口超出了左边界,则将其移动到右侧
if window_x < -total_width / 2:
window_x = window_width / 2
# 运行代码后,你将看到一个七段数码管式的学号在窗口中滚动,从右侧向左侧滚动,从左侧移出后重新出现在右侧,循环往复。
