python简单画钟代码(python画静态时钟)

Python不仅可以用于数据分析、机器学习等领域，还可以用于图像处理。下面，我们将使用Python的turtle模块绘制一个静态时钟。

import turtle
import time
# 绘制钟表轮廓
def draw_clock(radius):
pen = turtle.Turtle()
pen.speed(0)
pen.penup()
pen.goto(0, -radius)
pen.pendown()
pen.circle(radius)
pen.penup()
pen.goto(0,0)
pen.setheading(90)
# 绘制刻度线
for i in range(12):
pen.fd(radius*0.8)
pen.pendown()
pen.fd(radius*0.15)
pen.penup()
pen.goto(0,0)
pen.rt(30)
# 绘制时针、分针和秒针
hour = turtle.Turtle()
hour.speed(0)
hour.shape("turtle")
hour.color("blue")
hour.shapesize(1, 5)
hour.penup()
minute = turtle.Turtle()
minute.speed(0)
minute.shape("turtle")
minute.color("green")
minute.shapesize(1, 8)
minute.penup()
second = turtle.Turtle()
second.speed(0)
second.shape("turtle")
second.color("red")
second.shapesize(1, 10)
second.penup()
while True:
h = int(time.strftime("%I"))
m = int(time.strftime("%M"))
s = int(time.strftime("%S"))
hour.goto(0,0)
minute.goto(0,0)
second.goto(0,0)
hour.setheading(360/12 * (h + m/60))
minute.setheading(360/60 * m)
second.setheading(360/60 * s)
hour.pendown()
hour.fd(radius*0.5)
hour.penup()
minute.pendown()
minute.fd(radius*0.7)
minute.penup()
second.pendown()
second.fd(radius*0.9)
second.penup()
time.sleep(1)
# 主函数，设置画布大小
def main():
turtle.setup(600, 600)
draw_clock(200)
turtle.done()
if __name__ == "__main__":
main()

通过turtle模块，我们可以轻松地绘制出时钟的轮廓和各个部分。在绘制过程中，我们必须要注意函数之间的调用顺序以及每个部分的坐标和角度设置。中间的while语句负责更新时针、分针和秒针的角度，并在屏幕上进行不断刷新，从而实现时钟的运行效果。
