如何在python上绘制时钟？（没有时针或分针的时钟，只有一个图表）

我试图用Python3 turtle创建一个时钟面的图片，但是数字没有正确对齐。帮点忙？谢谢这就是我到目前为止所做的：

import turtle

screen=turtle.Screen()
screen.bgcolor(135, 205, 250)

clock = turtle.Turtle()
clock.shape("square")

clock.speed(0)

hours = 6
minutes = 30 

angle = 12

for i in range(angle):
    # draw the leg
    clock.forward(65)
    clock.right(30)
    clock.write(i)

    # go back to the middle and turn back around
    clock.right(180)
    clock.forward(65)
    clock.right(180)
    clock.write(i+1)

clock.shape("circle")
clock.forward(65)

screen.exitonclick()

---

您可以使用

align=“center”

控制

write（）

语句中文本的水平对齐。要垂直对齐字体，您必须使用

.sety（）

调整位置，考虑字体的垂直尺寸，如的答案所示。您使用

bgcolor（135、205、250）

时没有先调用

colormode（255）

使我怀疑您使用的是非标准字体（Repl）或Python turtle的旧版本。如果是这样的话，您应该说明这些问题，以避免在提供的答案中出现不兼容

下面是我如何解决这个问题。关键是要了解字体高度，以便进行更正：

from turtle import Screen, Turtle

FONT_SIZE = 12
FONT = ('Arial', FONT_SIZE, 'normal')

RADIUS = 65

screen = Screen()

clock = Turtle()
clock.shape('circle')
clock.speed('fastest')

for hour, angle in enumerate(range(60, -300, -30), start=1):
    clock.setheading(angle)
    position = clock.position()
    clock.forward(RADIUS)
    clock.penup()
    clock.forward(FONT_SIZE)
    clock.sety(clock.ycor() - 2 * FONT_SIZE/3)
    clock.write(hour, align='center', font=FONT)
    clock.setposition(position)
    clock.pendown()

screen.mainloop()

---

但是，使用指定的字体大小是一个粗略的猜测，在某些系统上可能会很糟糕。如果您是这样，那么您可以使用此答案中的基础tkinter函数调用获得字体高度的准确值，我假设您在发布自己的问题之前已在搜索SO时查看了此函数。

@cdlane回答正确-但这里还有一个带日期的时钟
