如何使用“turtle"将文本居中Python中的模块 [英] How to center text using "turtle" module in Python

问题描述

如何从窗口中心开始绘制turtle"文本?我知道如何创建海龟"文本，但我不知道如何将文本居中，使其从窗口中心显示.

How can I draw "turtle" text starting from the center of a window? I know how to create "turtle" text, but I don't know how to center the text so it appears from the center of a window.

turtle.write("I AM HERE", font=("Arial", 50, "bold"))

感谢您的帮助，

推荐答案

要将文本居中于一个点(例如原点在 [0, 0])，在 X 维度上，您可以使用 align=center turtle.write() 的关键字参数.要在 Y 维度上对齐，您需要稍微调整字体大小:

To center text on a point (e.g. the origin at [0, 0]), in the X dimension, you can use the align=center keyword argument to turtle.write(). To get alignment in the Y dimension, you need to adjust slightly for the font size:

from turtle import Turtle, Screen

FONT_SIZE = 50

FONT = ("Arial", FONT_SIZE, "bold")

yertle = Turtle()

# The turtle starts life in the center of the window
# but let's assume we've been drawing other things
# and now need to return to the center of the window

yertle.penup()
yertle.home()

# By default, the text prints too high unless we roughly
# readjust the baseline, you can confirm text placement
# by doing yertle.dot() after yertle.home() to see center

yertle.sety(-FONT_SIZE/2)

yertle.write("I AM HERE", align="center", font=FONT)

yertle.hideturtle()

screen = Screen()

screen.exitonclick()

但是，如果您想从中心开始打印(您的帖子不清楚)，您可以将 align=center 更改为 align=left，或者只是完全省略 align 关键字参数.

However if you instead want to start printing from the center (your post isn't clear), you can change align=center to align=left, or just leave out the align keyword argument altogether.
