python钟表代码

以下是一个简单的 Python 钟表代码：

import time

while True:
    current_time = time.strftime("%H:%M:%S", time.localtime())
    print(current_time, end="\r")
    time.sleep(1)

这个程序会在命令行中不断输出当前时间，并且每秒钟更新一次。你可以通过按下 Ctrl+C 来停止程序的运行。

python 绘制时钟表盘具体代码

以下是 Python 绘制时钟表盘的代码示例：

import turtle
import time

# 设置窗口的大小
window = turtle.Screen()
window.setup(width=600, height=600)
window.bgcolor('white')

# 设置海龟的初始位置和方向
pen = turtle.Turtle()
pen.penup()
pen.goto(0, 0)
pen.setheading(90)

# 绘制时钟刻度
for i in range(12):
    pen.penup()
    pen.forward(250)
    pen.pendown()
    pen.forward(25)
    pen.penup()
    pen.backward(275)
    pen.right(30)

# 绘制时针、分针和秒针
hour = turtle.Turtle()
hour.penup()
hour.goto(0, 0)
hour.pendown()
hour.pensize(4)

minute = turtle.Turtle()
minute.penup()
minute.goto(0, 0)
minute.pendown()
minute.pensize(3)

second = turtle.Turtle()
second.penup()
second.goto(0, 0)
second.pendown()
second.pensize(2)

while True:
    # 获取当前时间
    h = int(time.strftime('%I'))
    m = int(time.strftime('%M'))
    s = int(time.strftime('%S'))

    # 设置时针、分针和秒针的角度
    hour.setheading(30 * h + m / 2)
    minute.setheading(6 * m)
    second.setheading(6 * s)

    # 绘制时针、分针和秒针的指针
    hour.forward(100)
    minute.forward(180)
    second.forward(200)

    # 更新画面
    window.update()

    # 重置画板
    hour.penup()
    hour.goto(0, 0)
    hour.pendown()

    minute.penup()
    minute.goto(0, 0)
    minute.pendown()

    second.penup()
    second.goto(0, 0)
    second.pendown()

    # 等待一秒钟
    time.sleep(1)

# 关闭窗口
window.exitonclick()

python海龟画图钟表

python海龟画图钟表的实现可以参考以下示例代码：

import turtle
import datetime

# 设置窗体大小
turtle.setup(600, 600)
# 隐藏箭头
turtle.hideturtle()

# 绘制表盘
turtle.penup()
turtle.goto(0, -200)
turtle.pendown()
turtle.circle(200)

# 绘制刻度
turtle.penup()
turtle.goto(0, 0)
turtle.setheading(90)

for _ in range(12):
    turtle.penup()
    turtle.forward(170)
    turtle.pendown()
    turtle.forward(30)
    turtle.penup()
    turtle.goto(0, 0)
    turtle.right(30)

# 绘制时针、分针、秒针
current_time = datetime.datetime.now()
hour = current_time.hour % 12
minute = current_time.minute
second = current_time.second

# 时针
turtle.penup()
turtle.goto(0, 0)
turtle.setheading(90)
turtle.right(hour * 30 + minute * 0.5)
turtle.pendown()
turtle.forward(100)

# 分针
turtle.penup()
turtle.goto(0, 0)
turtle.setheading(90)
turtle.right(minute * 6 + second * 0.1)
turtle.pendown()
turtle.forward(150)

# 秒针
turtle.penup()
turtle.goto(0, 0)
turtle.setheading(90)
turtle.right(second * 6)
turtle.pendown()
turtle.forward(180)

# 不关闭窗体
turtle.mainloop()
