在Python Turtle中绘制填充颜色的形状

turtle是python中的一个内置模块。它提供了使用屏幕（纸板）和Turtle（笔）的绘画。为了在屏幕上画东西，我们需要移动Turtle。为了移动Turtle，有一些函数，如forward(), backward()等。

为了在turtle绘制的图形中填充颜色，turtle提供了三个函数–

fillcolor() 。这有助于选择用于填充形状的颜色。它将输入参数作为颜色名称或颜色的十六进制值，并将所选的颜色填充到即将封闭的地理对象中。颜色名称是基本的颜色名称，即红色、蓝色、绿色、橙色。
颜色的十六进制值是一串（以’#’开头）的十六进制数字，即：#RRGGBB。R、G和B是十六进制数字（0、1、2、3、4、5、6、7、8、9、A、B、C、D、E、F）。

begin_fill() 。这个函数告诉Turtle，所有即将关闭的图形对象需要被选定的颜色填充。

end_fill() : 这个函数告诉Turtle停止填充即将关闭的图形对象。
