源代码
python引入两个内置库turtle和datetime即可制作一个实时钟表,代码如下:
# 用turtle画时钟
# 以自定义shape的方式实现
import turtle as t
import datetime as d
def skip(step): # 抬笔,跳到一个地方
t.penup()
t.forward(step)
t.pendown()
def drawClock(radius): # 画表盘
t.speed(0)
t.mode("logo") # 以Logo坐标、角度方式
t.hideturtle()
t.pensize(7)
t.home() # 回到圆点
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): # 钟的指针,时针、分针、秒针
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) # 注册为一个shape
def drawPoint(): # 画指针
global hourPoint, minPoint, secPoint, fontWriter
makePoint("hourPoint", 100)
makePoint("minPoint", 120)
makePoint("secPoint", 140)
hourPoint = t.Pen() # 每个指针是一只新turtle
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):
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 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)
# 用turtle写文字
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) # 每隔1000毫秒调用一次realTime()
def main():
t.tracer(False)
drawClock(160)
drawPoint()
getRealtime()
t.tracer(True)
t.mainloop()
if __name__ == '__main__':
main()
引用模块:turtle,datetime
定义函数:
- skip():重复指定动作
- drawClock():画表盘
- drawPoint():画指针
- getWeek():显示星期
- getDate():显示日期
- getRealtime():显示实时时间
- main():主函数
运行效果如下:
打包exe
也可打包为exe,这样在没有编译环境的情况下也可以运行(发给你的小伙伴展示一下你的技术,岂不美哉) 效果如下(不会打包看pyinstaller打包exe详细教程) 这里就不做演示了,直接上效果图
以上就是利用turtle库和datetime库制作实时钟表
到此这篇关于python 使用turtle实现实时钟表并生成exe的文章就介绍到这了,更多相关python 实时钟表内容请搜索编程网以前的文章或继续浏览下面的相关文章希望大家以后多多支持编程网!
