用Python模拟同步时钟

用Python模拟同步时钟

首先：导包

form turtle import
form datetime import

其次

def Skip(step):
penup()
forward(step)
pendown()

注册，建立表针Turtle

def mkHand(name, length):
reset()
Skip(-length*0.1)
begin_poly()
forward(length*1.1)
end_poly()
handForm = get_poly()
register_shape(name, handForm)

初始化表盘

def Init():
global secHand, minHand, hurHand, printer
mode("logo")
mkHand("secHand", 125)
mkHand("minHand",  130)
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)
printer = Turtle()
printer.hideturtle()
printer.penup()

建立表的外框

def SetupClock(radius):
reset()
pensize(7)
for i in range(60):
Skip(radius)
if i % 5 == 0:
forward(20)
Skip(-radius-20)
else:
dot(5)
Skip(-radius)
right

输入星期

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()]

输入年、月、日

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

定义动态表盘

def Tick():
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)

判断加以输出

def main():
tracer(False)
Init()
SetupClock(160)
tracer(True)
Tick()
mainloop()
if __name__ == "__main__":
main()

效果图如下
