使用turtle库、time库编程实现七段数码管式2,0,2,2,0,5,4,0,4,1,6,3按顺序 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

好的,我来为您编写代码实现这个功能。请先确保您已经安装了turtle库和time库。
```python
import turtle
import time
# 数码管的字典,每个数字对应的管道
digit_dict = {
"0": [(0, 50), (30, 50), (30, -50), (0, -50), (0, 50), (0, 0)],
"1": [(0, 50), (0, -50)],
"2": [(0, 50), (30, 50), (30, 0), (0, 0), (0, -50), (30, -50)],
"3": [(0, 50), (30, 50), (30, 0), (0, 0), (30, 0), (30, -50), (0, -50)],
"4": [(0, 50), (0, 0), (30, 0), (30, 50), (30, -50)],
"5": [(30, 50), (0, 50), (0, 0), (30, 0), (30, -50), (0, -50)],
"6": [(30, 50), (0, 50), (0, -50), (30, -50), (30, 0), (0, 0)],
"7": [(0, 50), (30, 50), (30, -50)],
"8": [(0, 50), (30, 50), (30, -50), (0, -50), (0, 50), (30, 0), (0, 0)],
"9": [(0, 50), (30, 50), (30, 0), (0, 0), (0, -50), (30, -50)]
}
# 创建数码管turtle对象
def create_turtle():
t = turtle.Turtle()
t.penup()
t.speed(0)
t.hideturtle()
return t
# 画出单个数字
def draw_digit(digit, t):
for i in range(len(digit_dict[digit])):
x, y = digit_dict[digit][i]
t.goto(x, y)
t.pendown()
# 画出数字序列
def draw_number(number, t):
for digit in number:
draw_digit(digit, t)
t.penup()
t.goto(t.xcor() + 40, t.ycor())
t.pendown()
# 滚动数字序列
def scroll_number(number, t):
for i in range(len(number)):
t.clear()
draw_number(number[i:] + number[:i], t)
time.sleep(0.5)
# 主函数
def main():
number = "202205404163"
t = create_turtle()
while True:
scroll_number(number, t)
if __name__ == "__main__":
main()
```
这个程序会在窗口中不断滚动数字序列,直到您手动停止程序。
