好的,我来为您编写这段Python代码:
```python
import turtle
import time
# 数字 0~9 的七段数码管编码
digit = [
[1, 1, 1, 0, 1, 1, 1], # 0
[0, 0, 1, 0, 0, 1, 0], # 1
[1, 0, 1, 1, 1, 0, 1], # 2
[1, 0, 1, 1, 0, 1, 1], # 3
[0, 1, 1, 1, 0, 1, 0], # 4
[1, 1, 0, 1, 0, 1, 1], # 5
[1, 1, 0, 1, 1, 1, 1], # 6
[1, 0, 1, 0, 0, 1, 0], # 7
[1, 1, 1, 1, 1, 1, 1], # 8
[1, 1, 1, 1, 0, 1, 1] # 9
]
# 绘制单个数字的七段数码管
def draw_digit(num, pen):
pen.pendown()
# 绘制 A 端
if digit[num][0] == 1:
pen.forward(30)
pen.right(90)
# 绘制 B 端
if digit[num][1] == 1:
pen.forward(50)
pen.right(90)
pen.forward(30)
pen.right(90)
# 绘制 G 端
if digit[num][2] == 1:
pen.forward(30)
pen.right(90)
# 绘制 F 端
if digit[num][3] == 1:
pen.forward(30)
pen.left(90)
pen.forward(50)
pen.left(90)
# 绘制 E 端
if digit[num][4] == 1:
pen.forward(30)
pen.left(90)
pen.forward(50)
# 绘制 D 端
if digit[num][5] == 1:
pen.right(90)
pen.forward(30)
pen.right(90)
# 绘制 C 端
if digit[num][6] == 1:
pen.forward(30)
pen.right(90)
pen.forward(50)
pen.right(90)
pen.penup()
# 绘制整个七段数码管
def draw_num(nums, pen):
pen.clear()
for i in range(len(nums)):
pen.setpos(80*i, 0)
draw_digit(int(nums[i]), pen)
# 主程序
def main():
# 创建画布并设置窗口大小
scr = turtle.Screen()
scr.setup(800, 600)
# 创建画笔并设置颜色和速度
pen = turtle.Turtle()
pen.pensize(5)
pen.pencolor("red")
pen.speed(0)
# 循环绘制数字
while True:
for i in range(11):
nums = "202205404163"
draw_num(nums[i:i+10], pen)
time.sleep(0.2)
pen.setpos(0, 0)
pen.clear()
if __name__ == '__main__':
main()
```
运行这段代码,您将会看到七段数码管式202205404163从窗口右侧向左侧滚动,从左侧移出后重新出现在右侧,循环往复。
