使用turtle库、time库编程实现七段数码管数字时钟

好的，以下是使用Turtle库和Time库编写的Python程序，实现七段数码管数字时钟：

import turtle
import time

# 定义数字对应的七段数码管状态
digit_states = {
    0: [1, 1, 1, 1, 1, 1, 0],
    1: [0, 1, 1, 0, 0, 0, 0],
    2: [1, 1, 0, 1, 1, 0, 1],
    3: [1, 1, 1, 1, 0, 0, 1],
    4: [0, 1, 1, 0, 0, 1, 1],
    5: [1, 0, 1, 1, 0, 1, 1],
    6: [1, 0, 1, 1, 1, 1, 1],
    7: [1, 1, 1, 0, 0, 0, 0],
    8: [1, 1, 1, 1, 1, 1, 1],
    9: [1, 1, 1, 1, 0, 1, 1]
}

# 定义画七段数码管的函数
def draw_digit(digit, color):
    turtle.pendown() if digit_states[digit][0] else turtle.penup()
    turtle.left(90)
    turtle.forward(40)
    turtle.right(90)
    turtle.pendown() if digit_states[digit][1] else turtle.penup()
    turtle.forward(20)
    turtle.right(90)
    turtle.pendown() if digit_states[digit][2] else turtle.penup()
    turtle.forward(20)
    turtle.right(90)
    turtle.pendown() if digit_states[digit][3] else turtle.penup()
    turtle.forward(20)
    turtle.left(90)
    turtle.pendown() if digit_states[digit][4] else turtle.penup()
    turtle.forward(20)
    turtle.left(90)
    turtle.pendown() if digit_states[digit][5] else turtle.penup()
    turtle.forward(20)
    turtle.left(90)
    turtle.pendown() if digit_states[digit][6] else turtle.penup()
    turtle.forward(20)
    turtle.right(180)
    turtle.penup()
    turtle.forward(20)
    turtle.left(90)
    turtle.forward(40)
    turtle.right(90)

# 设置画布和画笔
turtle.setup(800, 600)
turtle.speed(0)
turtle.hideturtle()
turtle.penup()
turtle.goto(-150, 0)

# 循环绘制数字时钟
while True:
    # 获取当前时间
    current_time = time.strftime("%H%M%S", time.localtime())

    # 清空画布
    turtle.clear()

    # 绘制数字时钟
    for i, digit in enumerate(current_time):
        turtle.color("red")
        if i == 2:  # 冒号
            turtle.penup()
            turtle.forward(40)
            turtle.pendown()
            turtle.circle(10)
            turtle.penup()
            turtle.backward(40)
            turtle.right(90)
            turtle.forward(40)
            turtle.left(90)
        else:  # 数字
            draw_digit(int(digit), "red")

    # 刷新画布
    turtle.update()

    # 暂停一秒钟
    time.sleep(1)

运行这个程序，将会在窗口中显示出一个七段数码管数字时钟，每秒钟更新一次。
