叮叮叮，我们要按时长大

我是你们的木子同学！当当当当——隆重出场，撒花撒花~

嗨！大家有没有生物钟不准时的时候，是不是每到休息日或者长假就会经常要倒时差？

每天上班最痛苦的事情就是早起早起早起！这是大部分上班族的痛苦，但是不上班又是不可能的啦，因为都是为了搞钱

今天小编就用代码示例化，给大家展示一下不同的时钟，希望大家按时上班，按时搞钱啦

一、Turtle绘制时钟

1）代码展示

import turtle
from datetime import *

# 抬起画笔，向前运动一段距离放下
def Skip(step):
    turtle.penup()
    turtle.forward(step)
    turtle.pendown()

def mkHand(name, length):
    # 注册Turtle形状，建立表针Turtle
    turtle.reset()
    Skip(-length * 0.1)
    # 开始记录多边形的顶点。当前的乌龟位置是多边形的第一个顶点。
    turtle.begin_poly()
    turtle.forward(length * 1.1)
    # 停止记录多边形的顶点。当前的乌龟位置是多边形的最后一个顶点。将与第一个顶点相连。
    turtle.end_poly()
    # 返回最后记录的多边形。
    handForm = turtle.get_poly()
    turtle.register_shape(name, handForm)

def Init():
    global secHand, minHand, hurHand, printer
    # 重置Turtle指向北
    turtle.mode("logo")
    # 建立三个表针Turtle并初始化
    mkHand("secHand", 135)
    mkHand("minHand", 125)
    mkHand("hurHand", 90)
    secHand = turtle.Turtle()
    secHand.shape("secHand")
    minHand = turtle.Turtle()
    minHand.shape("minHand")
    hurHand = turtle.Turtle()
    hurHand.shape("hurHand")

    for hand in secHand, minHand, hurHand:
        hand.shapesize(1, 1, 3)
        hand.speed(0)

    # 建立输出文字Turtle
    printer = turtle.Turtle()
    # 隐藏画笔的turtle形状
    printer.hideturtle()
    printer.penup()

def SetupClock(radius):
    # 建立表的外框
    turtle.reset()
    turtle.pensize(7)
    for i in range(60):
        Skip(radius)
        if i % 5 == 0:
            turtle.forward(20)
            Skip(-radius - 20)

            Skip(radius + 20)
            if i == 0:
                turtle.write(int(12), align="center", font=("Courier", 14, "bold"))
            elif i == 30:
                Skip(25)
                turtle.write(int(i/5), align="center", font=("Courier", 14, "bold"))
                Skip(-25)
            elif (i == 25 or i == 35):
                Skip(20)
                turtle.write(int(i/5), align="center", font=("Courier", 14, "bold"))
                Skip(-20)
            else:
                turtle.write(int(i/5), align="center", font=("Courier", 14, "bold"))
            Skip(-radius - 20)
        else:
            turtle.dot(5)
            Skip(-radius)
        turtle.right(6)

def Week(t):
    week = ["星期一", "星期二", "星期三",
            "星期四", "星期五", "星期六", "星期日"]
    return week[t.weekday()]

def Date(t):
    y = t.year
    m = t.month
    d = t.da
    return "%s %d%d" % (y, m, d)

def Tick():
    # 绘制表针的动态显示
    t = datetime.today()
    second = t.second + t.microsecond * 0.000001
    minute = t.minute + second / 60.0
    hour = t.hour + minute / 60.0
    secHand.setheading(6 * second)
    minHand.setheading(6 * minute)
    hurHand.setheading(30 * hour)

    turtle.tracer(False)
    printer.forward(65)
    printer.write(Week(t), align="center",
                  font=("Courier", 14, "bold"))
    printer.back(130)
    printer.write(Date(t), align="center",
                  font=("Courier", 14, "bold"))
    printer.hom()
    turtle.tracer(True)

    # 100ms后继续调用tick
    turtle.ontimer(Tick, 100)

def main():
    # 打开/关闭龟动画，并为更新图纸设置延迟。
    turtle.tracer(False)
    Init()
    SetupClock(160)
    turtle.tracer(True)
    Tick()
    turtle.mainloop()

if __name__ == "__main__":
    main()

二、Turtle实现模拟时钟

1）代码展示

基本思路：自定义shape，画出时针、分针、秒针。通过register_shape()函数。 指针的位置通过shape类setheading()函数进行设置。 获取系统时间作为当前时间，datetime.today()。 利用ontimer()函数定义定时器事件，触发屏幕更新。 利用write()函数在屏幕上显示文本。

from turtle import *
from datetime import datetime

mode("logo") # 向上（北），正角度为顺时针

thisday = 0
thisecond = 0

second_hand = Turtle()
minute_hand = Turtle()
hour_hand = Turtle()
writer = Turtle()
writer.getscreen().bgcolor('gray90')
writer.color("gray20", "gray20")

def jump(distanz, winkel=0):
    penup()
    right(winkel)
    forward(distanz)
    left(winkel)
    pendown()
'''
laenge 指针长度
width 指针宽度
spitze 箭头边长
'''
def hand(laenge, spitze, width):
    lt(90)
    fd(width)
    rt(90)
    fd(laenge*1.15)
    rt(90)
    fd(width * 2)
    rt(90)
    fd(laenge*1.15)
    rt(90)
    fd(width)
    rt(90)
    fd(laenge*1.15)
    rt(90)
    fd(spitze/2.0)
    lt(120)
    fd(spitze)
    lt(120)
    fd(spitze)
    lt(120)
    fd(spitze/2.0)

def make_hand_shape(name, laenge, spitze, width):
    reset()

    for i in range(60):
        jump(radius)
        if i % 5 == 0:
            fd(-15)

            jump(params[i/5], angles[i/5])
