蟒蛇龟笔颜色 [英] Python Turtle pen colour

问题描述

当我调用 t.pencolor('83, 58, 27')(乌龟被导入为 t)时，我得到 TurtleGraphicsError: bad color string: 83, 58, 27 即使我(我认为)改变了我的颜色模式.

When I call t.pencolor('83, 58, 27') (turtle is imported as t) I get the TurtleGraphicsError: bad color string: 83, 58, 27 even though I have (I think) changed my colour mode.

t.colormode(255)    
t.pencolor('83, 58, 27')

我在 OS 10.9 上运行 python 2.7

推荐答案

你传入了一个带有三种颜色的字符串，你需要将这三种颜色作为三个单独的整数参数传递，像这样:

You are passing in a string with three colors, where you need to pass the three colors as three separate integer arguments, like this:

t.pencolor(83, 58, 27)

有多种使用 pencolor 的方法，来自 文档:

There are multiple ways to use pencolor, from the documentation:

允许四种输入格式:

钢笔颜色()将当前画笔颜色作为颜色规范字符串或元组返回(参见示例).可以用作另一个的输入color/pencolor/fillcolor 调用.

pencolor() Return the current pencolor as color specification string or as a tuple (see example). May be used as input to another color/pencolor/fillcolor call.

pencolor(colorstring)将 pencolor 设置为 colorstring，即 Tk 颜色规范字符串，例如red"、yellow"或#33cc8c".

pencolor(colorstring) Set pencolor to colorstring, which is a Tk color specification string, such as "red", "yellow", or "#33cc8c".

pencolor((r, g, b))将 pencolor 设置为由 r、g 和 b 的元组表示的 RGB 颜色.r、g 和 b 中的每一个都必须在 0..colormode 范围内，其中colormode 为 1.0 或 255(请参阅 colormode()).

pencolor((r, g, b)) Set pencolor to the RGB color represented by the tuple of r, g, and b. Each of r, g, and b must be in the range 0..colormode, where colormode is either 1.0 or 255 (see colormode()).

pencolor(r, g, b)将 pencolor 设置为由 r、g 和 b 表示的 RGB 颜色.r、g 和 b 中的每一个都必须在 0..colormode 范围内.

pencolor(r, g, b) Set pencolor to the RGB color represented by r, g, and b. Each of r, g, and b must be in the range 0..colormode.

所以你也可以发送一个元组你的颜色，但同样它们需要是整数而不是字符串:

So you can also send in a tuple of your colors, but again they need to be integers not strings:

t.pencolor((83, 58, 27))
