Question

以下代码仅适用于饰品，并且在其他IDE（例如pyCharm，Jupytor和IDLE）上运行时，会出现很多错误。

我也尝试过在在线编译器中执行此代码，但是有很多错误。

当我在饰品中执行此代码时，错误为零。

    red = randint(0, 255)
    green = randint(0, 255)

    color(red, green, blue )

    penup()
    x = randint(-100,100)
    y = randint(-100,100)
    goto(x,y)

    heading = randint(0, 360)
    setheading(heading)

您传入的RGB值为0到255。默认情况下，乌龟中的颜色模式为0到1.0。因此，您需要先将颜色模式设置为255，然后再尝试设置rgb值。或者您需要将rgb值设置在0到1.0之间。

turtle.color说

    """Return color string corresponding to args.

    Argument may be a string or a tuple of three
    numbers corresponding to actual colormode,
    i.e. in the range 0<=n<=colormode.

    If the argument doesn't represent a color,
    an error is raised.
    """

颜色模式可以是1.0或255。因此默认情况下，颜色模式为1.0，因此颜色具有此代码。

   if self._colormode == 1.0:
        r, g, b = [round(255.0*x) for x in (r, g, b)]
    if not ((0 <= r <= 255) and (0 <= g <= 255) and (0 <= b <= 255)):
        raise TurtleGraphicsError("bad color sequence: %s" % str(color))

所以可以说您将100、100、100分别作为RGB传递，但是色彩模式当前设置为1.0。然后颜色会将所有RGB乘以255.0。因此，您的rgb将变为25500、25500、25500。然后，颜色将检查每个RGB是否在0和255之间（包括0和255），但是由于颜色将所有rgb乘以255，因为颜色模式为1.0，因此所有rgb现在都超过255，因此颜色差颜色序列异常。

因此，要么将颜色模式设置为255，要么在0和1之间传递rgb值

255 RGB

from turtle import *
from random import *

colormode(255)
def randomcolour():
    red = randint(0, 255)
    green = randint(0, 255)
    blue = randint(0, 255)
    color(red, green, blue )

浮点数RGB

from turtle import *
from random import *

def randomcolour():
    red = uniform(0, 1)
    green = uniform(0, 1)
    blue = uniform(0, 1)
    color(red, green, blue )

关于它在小饰品中工作，但在其他饰品中却不行，也许小饰品正在将您的颜色模式设置为255

为什么我的以下代码无法在Trinket之外的任何其他IDE中运行？
