好吧，让我们先设置一些我们需要使用的函数：
首先是main()主函数(老板)
然后我们需要一个画钟的函数—— drawClock()和skip()
然后我们需要一个函数来获得正确的时间——getRealtime()，getWeek(),getDate()
最重要的是画指针的函数——makePoint(),drawPoint()
程序：
import turtle as t import datetime as d def skip(step): t.penup() t.forward(step) t.pendown() def drawClock(radius): t.speed(0) t.mode("logo") t.hideturtle() t.pensize(7) t.home() for j in range(60): skip(radius) if (j % 5 == 0): t.forward(20) skip(-radius - 20) else: t.dot(5) skip(-radius) t.right(6) def makePoint(pointName, len): t.penup() t.home() t.begin_poly() t.back(0.1 * len) t.forward(len * 1.1) t.end_poly() poly = t.get_poly() t.register_shape(pointName, poly) def drawPoint(): global hourPoint, minPoint, secPoint, fontWriter makePoint("hourPoint", 100) makePoint("minPoint", 120) makePoint("secPoint", 140) hourPoint = t.Pen() hourPoint.shape("hourPoint") hourPoint.shapesize(1, 1, 6) minPoint = t.Pen() minPoint.shape("minPoint") minPoint.shapesize(1, 1, 4) secPoint = t.Pen() secPoint.shape("secPoint") secPoint.pencolor('red') fontWriter = t.Pen() fontWriter.pencolor('gray') fontWriter.hideturtle() def getWeek(weekday): return "%s%s" %("星期",weekday 1) def getDate(year, month, day): return "%s-%s-%s" % (year, month, day) def getRealtime(): curr = d.datetime.now() curr_year = curr.year curr_month = curr.month curr_day = curr.day curr_hour = curr.hour curr_minute = curr.minute curr_second = curr.second curr_weekday = curr.weekday() t.tracer(False) secPoint.setheading(360 / 60 * curr_second) minPoint.setheading(360 / 60 * curr_minute) hourPoint.setheading(360 / 12 * curr_hour 30 / 60 * curr_minute) fontWriter.clear() fontWriter.home() fontWriter.penup() fontWriter.forward(80) fontWriter.write(getWeek(curr_weekday), align="center", font=("Courier", 14, "bold")) fontWriter.forward(-160) fontWriter.write(getDate(curr_year, curr_month, curr_day), align="center", font=("Courier", 14, "bold")) t.tracer(True) print(curr_second) t.ontimer(getRealtime, 1000) def main(): t.tracer(False) drawClock(160) drawPoint() getRealtime() t.tracer(True) t.mainloop() main()
