1 问题 如何用Python画一个实时的时钟？ 2 方法 （1）安装turtle模块，turtle库是python的标准库之一，属于入门级的图形绘制函数库，通过它可以实现图像的生成。 （2）使用turtle库画图的特性画出时钟。 （3）最后通过自定义shape的方法完成绘制。 代码清单 1 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 getWeekName(weekday):
weekName = ['星期一', '星期二', '星期三', '星期四', '星期五', '星期六', '星期日']
return weekName[weekday]
def getDate(year, month, day):
return "%s-%s-%s" % (year, month, day)
def realTime():
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(getWeekName(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(realTime, 100)
def main():
t.tracer(False)
drawClock(160)
drawPoint()
realTime()
t.tracer(True)
t.mainloop()
if __name__ == '__main__':
main() |
3 结语 针对制作简易的实时时钟问题，经过测试，证明可以通过使用turtle模块实现。之后还可以优化：例如加入每个小点所对应的具体数字，以及该天所对应的天气，不断的完善该程序。
