用Python画了一个钟

用python画了一个钟

代码如下

import turtle as t
import datetime as d
import math


def skip(step):
    # 跳跃给定的距离
    t.penup()
    t.fd(step)
    t.pendown()


# 时钟的头部
def clock_hand():
    t.bgcolor("yellow")
    t.pensize(5)
    t.color("black")
    t.right(90)
    t.color("black", 'green')
    t.begin_fill()
    t.circle(50, 360)
    t.end_fill()
    t.up()
    t.left(90)
    t.fd(60)

    t.left(90)
    t.up()
    t.fd(20)
    t.down()
    t.color("black")
    t.dot(20)  # 画一个点
    t.write("溪山看未足，还听暮楼钟。", align="center", font=("演示悠然小楷", 35, "bold"))
    t.up()
    t.fd(-40)
    t.down()
    t.color("black")

        skip(radius)
        if i % 5 == 0:
            # 画一条直线
            t.color("black")
            t.write(a, align="center", font=("演示悠然小楷", 30, "bold"))
            a = a+1
            t.color("red")
            t.forward(20)

                clock_hand()
            if i == 30:
                t.up()
                t.fd(-60)
                t.down()
                t.color("blue")
                t.write("时钟", align="center", font=("演示悠然小楷", 30, "bold"))
                t.up()
                t.fd(60)
            skip(-radius - 20)
        else:
            t.color("green")
            t.dot(5)  # 画一个点
            skip(-radius)
        t.right(6)

    t.reset()
    skip(-length * 0.1)
    # 开始记录多变形的定点

        hand.speed(0)
        hands.append(hand)
    secHand, minHand, hourHand = hands
    printer = t.Turtle()
    printer.hideturtle()
    printer.penup()


def draw_hand(time):
    second = time.second + time.microsecond * 0.000001
    minute = time.minute + time.second / 60.0
    hour = time.hour + time.minute / 60.0
    secHand.setheading(second * 6)
    minHand.setheading(minute * 6)
    hourHand.setheading(hour * 30)


def week(time):
    week = ["星期一", "星期二", "星期三", "星期四", "星期五", "星期六", "星期天"]
    return week[time.weekday()]


def day(time):
    return f'{time.year} {time.month} {time.day}'


def name():
    return "为了理想"


def draw_date(time):
    t.tracer(False)
    printer.forward(70)
    printer.write(week(time), align="center", font=("演示悠然小楷", 18, 'bold'))
    printer.back(130)
    printer.write(day(time), align='center', font=('演示悠然小楷', 14, 'bold'))
    printer.forward(30)
    printer.write(name(), align="right", font=('演示悠然小楷', 18, 'bold'))
    printer.home()
    t.tracer(True)


def tick():
    time = d.datetime.today()
    draw_hand(time)
    draw_date(time)
    t.ontimer(tick, 200)


if __name__ == "__main__":
    # 关闭绘画跟踪，可以用于加速绘图
    t.tracer(False)
    init()
    setup_clock(200)
    t.tracer(True)
    tick()
    t.hideturtle()
    t.done()

运行结果如下

我用的字体电脑一般不会自带，我用的是小楷字体。比较喜欢这种字体。看起来很舒服。
