python ——钟表

1、表盘

 from turtle import *
 from datetime import *

 def Skip(step):#表盘不连续地画图
     penup()
     forward(step)
     pendown()

 def SetupClock(radius):
     #建立表的外框
     reset()
     pensize(7)
     for i in range(60):
         Skip(radius)#跨越中间这段不画
         if i % 5 == 0:
             forward(20)
             Skip(-radius-20)#抬起画笔，回到原处
         else:
             dot(5)
             Skip(-radius)#抬起画笔，回到圆心
         right(6)#回到圆心，方向旋转6度

 SetupClock(160)

2、添加指针

 from turtle import *
 from datetime import *

 def Skip(step):#表盘不连续地画图
     penup()
     forward(step)
     pendown()

 def mkHand(name, length):
     #注册Turtle形状，建立表针Turtle
     #清空窗口，重置默认值
     Skip(-length*0.1)#先回一点
     begin_poly()#初始点
     forward(length*1.1)
     end_poly()#结束点
     handForm = get_poly()#返回最后记录的多边形
     register_shape(name, handForm)#寄存器形状，安装相应的多边形
     goto(0,0)

 def Init():
     global secHand, minHand, hurHand, printer
     mode("logo")# 重置Turtle指向北

     #建立三个表针Turtle并初始化
     mkHand("secHand", 125)
     right(30)
     mkHand("minHand",  110)
     right(30)
     mkHand("hurHand", 90)

     secHand = Turtle()
     secHand.shape("secHand")
     minHand = Turtle()
     minHand.shape("minHand")
     hurHand = 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()
     printer.hideturtle()
     printer.penup()

 #画表框
 def SetupClock(radius):
     #建立表的外框
     reset()
     pensize(7)
     for i in range(60):
         Skip(radius)#跨越中间这段不画
         if i % 5 == 0:
             forward(20)
             Skip(-radius-20)#抬起画笔，回到原处
         else:
             dot(5)
             Skip(-radius)#抬起画笔，回到圆心
         right(6)#回到圆心，方向旋转6度

 Init()
 tracer(False)
 SetupClock(160）

3、时间

 from datetime import *
 from turtle import *

 #时分秒
 t = datetime.today()
 print(t)
 print(t.microsecond)
 print(t.second)
 second = t.second + t.microsecond*0.000001
 minute = t.minute + second/60.0
 hour = t.hour + minute/60.0

 #星期
 print(t.weekday())
 week = ["星期一", "星期二", "星期三",
             "星期四", "星期五", "星期六", "星期日"]
 print(week[t.weekday()])

 #年月日
 y = t.year
 m = t.month
 d = t.day
 # return "%s %d %d" % (y, m, d)
 print(y,"-",m,"-",d)

 tracer(False)
 mode("logo")# 重置Turtle指向北
 printer = Turtle()
 printer.forward(65)
 printer.write(week[t.weekday()], align="center",font=("Courier", 14, "bold"))#日期标在图中
 printer.back(130)
 printer.write("%d-%d-%d"%(y,m,d),align="center",font=("Courier", 14, "bold"))#日期标在图中

 from datetime import *
 from turtle import *

 #时分秒
 t = datetime.today()
 print(t)
 print(t.microsecond)
 print(t.second)
 second = t.second + t.microsecond*0.000001
 minute = t.minute + second/60.0
 hour = t.hour + minute/60.0

 #星期
 print(t.weekday())
 week = ["星期一", "星期二", "星期三",
             "星期四", "星期五", "星期六", "星期日"]
 print(week[t.weekday()])

 #年月日
 y = t.year
 m = t.month
 d = t.day
 # return "%s %d %d" % (y, m, d)
 print(y,"-",m,"-",d)

 tracer(False)
 mode("logo")# 重置Turtle指向北
 printer = Turtle()
 printer.hideturtle()
 printer.penup()#提起画笔，便没了那两道轨迹
 printer.forward(65)
 printer.write(week[t.weekday()], align="center",font=("Courier", 14, "bold"))#日期标在图中
 printer.back(130)
 printer.write("%s-%d-%d"%(y,m,d),align="center",font=("Courier", 14, "bold"))#日期标在图中
 printer.home()
 tracer(True)

 from datetime import *
 from turtle import *

 def Skip(step):#表盘不连续地画图
     penup()
     forward(step)
     pendown()

 def mkHand(name, length):
     #注册Turtle形状，建立表针Turtle
     #清空窗口，重置默认值
     Skip(-length*0.1)#先回一点
     begin_poly()#初始点
     forward(length*1.1)
     end_poly()#结束点
     handForm = get_poly()#返回最后记录的多边形
     register_shape(name, handForm)#寄存器形状，安装相应的多边形
     goto(0,0)

 def Init():
     global secHand, minHand, hurHand, printer
     mode("logo")# 重置Turtle指向北
     right(90)
     #建立三个表针Turtle并初始化
     mkHand("secHand", 125)
     right(30)
     mkHand("minHand",  110)
     right(30)
     mkHand("hurHand", 90)

     secHand = Turtle()
     secHand.shape("secHand")
     minHand = Turtle()
     minHand.shape("minHand")
     hurHand = 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()
     printer.hideturtle()
     printer.penup()

 #画表框
 def SetupClock(radius):
     #建立表的外框
     reset()
     pensize(7)
     for i in range(60):
         Skip(radius)#跨越中间这段不画
         if i % 5 == 0:
             forward(20)
             Skip(-radius-20)#抬起画笔，回到原处
         else:
             dot(5)
             Skip(-radius)#抬起画笔，回到圆心
         right(6)#回到圆心，方向旋转6度

 tracer(False)
 Init()
 SetupClock(160)
 tracer(True)

 #时分秒
 t = datetime.today()
 print(t)
 print(t.microsecond)
 print(t.second)
 second = t.second + t.microsecond*0.000001
 minute = t.minute + second/60.0
 hour = t.hour + minute/60.0

 #星期
 print(t.weekday())
 week = ["星期一", "星期二", "星期三",
             "星期四", "星期五", "星期六", "星期日"]
 print(week[t.weekday()])

 #年月日
 y = t.year
 m = t.month
 d = t.day
 # return "%s %d %d" % (y, m, d)
 print(y,"-",m,"-",d)

 tracer(False)
 #mode("logo")# 重置Turtle指向北
 printer = Turtle()
 printer.penup()
 printer.hideturtle()
 printer.forward(65)
 printer.write(week[t.weekday()], align="center",font=("Courier", 14, "bold"))#日期标在图中
 printer.back(130)
 printer.write("%d-%d-%d"%(y,m,d), align="center",font=("Courier", 14, "bold"))#日期标在图中
 tracer(True)

4、动态显示

将时间和角度对应起来，换算到角度，然后和指针对应起来

 from turtle import *
 from datetime import *

 def Skip(step):#表盘不连续地画图
     penup()
     forward(step)
     pendown()

 def mkHand(name, length):
     #注册Turtle形状，建立表针Turtle
     reset()
     Skip(-length*0.1)
     begin_poly()#多边形第一个顶点
     forward(length*1.1)
     end_poly()
     handForm = get_poly()
     register_shape(name, handForm)

 def Init():
     global secHand, minHand, hurHand, printer
     mode("logo")# 重置Turtle指向北,为后续角度提供便利
     #建立三个表针Turtle并初始化
     mkHand("secHand", 125)
     mkHand("minHand",  115)
     mkHand("hurHand", 90)
     secHand = Turtle()
     secHand.shape("secHand")
     minHand = Turtle()
     minHand.shape("minHand")
     hurHand = 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()
     printer.hideturtle()
     printer.penup()

 #画表框
 def SetupClock(radius):
     #建立表的外框
     reset()
     pensize(7)
     for i in range(60):
         Skip(radius)#跨越中间这段不画
         if i % 5 == 0:
             forward(20)
             Skip(-radius-20)#抬起画笔，回到原处
         else:
             dot(5)
             Skip(-radius)#抬起画笔，回到圆心
         right(6)#回到圆心，方向旋转6度

 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.day
     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)

     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.home()

     tracer(True)

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

 def main():
     tracer(False)#不刷新，最后一次刷新，省时间
     Init()
     SetupClock(160)
     tracer(True)
     Tick()
     mainloop()

 if __name__ == "__main__":
     main()
