Python 6行代码写北京时间时钟(10帧可调) 天地良心

今天看到别的大佬用Python写时钟

我密集恐惧症都犯了

十来个定义函数我看也看不懂

代码还有整整78行还是在我改良后的

改良前有98行我删注释优化函数名(比如把penup改成pu)

这个文件照样有5KB

并且在帧数取决于电脑性能我运行了一下电脑都卡出蓝屏了

于是我连夜赶工把这个6行的时钟搞出来了

在运行十分钟后也只有三十几MB

文件大小也只有723B

总之先放代码:

import turtle,time,datetime;date=datetime.datetime.now();turtle.tracer(0);mz=turtle.Turtle();fz=turtle.Turtle();fz.pensize(3);sz=turtle.Turtle();sz.pensize(5);bg=turtle.Turtle();bg.ht();bg.pu();bg.goto(0,-200)
for i in [6,5,4,3,2,1,12,11,10,9,8,7]:bg.write(i,font=('斜体',20,'normal'));bg.circle(200,30)
bg.goto(0,-210);bg.pd();bg.pensize(5);bg.circle(220)
def zd(pen,ds,cd):pen.clear();pen.pu();pen.goto(0,0);pen.pd();pen.right(ds);pen.fd(cd)
zd(mz,int(date.strftime('%S'))*6-90,180);zd(fz,int(date.strftime('%M'))*6-90,140);zd(sz,int(date.strftime('%H'))*30-90,100)
while 1:time.sleep(0.1);zd(mz,0.6,180);zd(fz,0.01,140);zd(sz,0.025/30,100);turtle.update()

现在是北京时间10:40

我运行一下程序是下图的效果:

_____________________________________________________________________________

下面是步骤

1.基础设置:

import datetime#导入datetime模块 负责获得当前时间
import turlte#导入turtle模块 负责图像显示
import time#导入time模块 负责调节帧率和减小电脑压力
date=datetime.datetime.now()#初始化datetime
turtle.tracer(0)#以最快速度运行

_____________________________________________________________________________

2.指针设置:

mz=turtle.Turtle()#创建秒针
fz=turtle.Turtle()#创建分针
fz.pensize(3)#把分针的宽度改为3像素
sz=turtle.Turtle()#创建时针
sz.pensize(5)#把时针的宽度改为5像素

_____________________________________________________________________________

3.表盘绘制:

bg=turtle.Turtle()#创建画笔bg
bg.ht()#隐藏画笔bg
bg.pu()#不让画笔bg留下痕迹
bg.goto(0,-200)#让画笔bg去0,-200的位置 这可以让圆心正好是0,0
for i in [6,5,4,3,2,1,12,11,10,9,8,7]:#让for循环遍历这个列表bg.write(i,font=('斜体',20,'normal'))#写出的字为当前列表中对应的数字bg.circle(200,30)#画一个圆的十二分之一
bg.goto(0,-210)#去圆外10像素的地方
bg.pd()#让画笔留下痕迹
bg.pensize(5)#把画笔bg的宽度改为5像素
bg.circle(220)#画一个半径为220的圆

_____________________________________________________________________________

4.转动函数:

def zd(pen,ds,cd):#定义函数zd("转动"的首字母)pen.clear()#清除这支画笔在这之前留下的痕迹pen.pu()#不让画笔留下痕迹pen.goto(0,0)#让画笔去中心pen.pd()#让画笔留下痕迹pen.right(ds)#让这只画笔右转(顺时针转)动ds度pen.fd(cd)#向前cd像素

_____________________________________________________________________________

5.转动:

zd(mz,int(date.strftime('%S'))*6-90,180)#获得秒
zd(fz,int(date.strftime('%M'))*6-90,140)#获得分
zd(sz,int(date.strftime('%H'))*30-90,100)#获得时
'''
date是之前初始化的datetime
strftime函数的参数里 特定的口令代表获得的时间(是字符串类型)
'''
while 1:time.sleep(0.1)#停止运行0.1秒(调节帧率 把一秒分成10帧)zd(mz,0.6,180)#秒针转动0.6° 长180像素zd(fz,0.01,140)#分针转动0.01° 长140像素zd(sz,0.025/30,100)#时针转动0.025/30°=0.3/360turtle.update()#刷新画面
#以下是调帧率的代码 变量a就是帧率 要自己填
'''
while 1:time.sleep(1/a)zd(mz,6/a,180)zd(fz,0.1/a,140)zd(sz,0.025/3/a)turtle.update()
'''
