在 Turtle 中绘制彩色填充形状 - Python

先决条件： Python Turtle 基础

turtle是Python中的一个内置模块。它使用屏幕（纸板）和海龟（笔）提供绘图。要在屏幕上绘制一些东西，我们需要移动海龟。要移动海龟，有一些函数，即forward() ， backward()等。

为了填充 turtle 绘制的形状中的颜色，turtle 提供了三个函数 -

fillcolor(): This helps to choose the color for filling the shape. It takes the input parameter as the color name or hex value of the color and fills the upcoming closed geographical objects with the chosen color. Color names are basic color names i.e. red, blue, green, orange.
The hex value of color is a string(starting with ‘#’) of hexadecimal numbers i.e. #RRGGBB. R, G, and B are the hexadecimal numbers (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F).

begin_fill(): This function tells turtle that all upcoming closed graphical objects needed to be filled by the chosen color.

end_fill(): this function tells turtle to stop the filling upcoming closed graphical objects.

# taking input for the side of the square
s = int(input("Enter the length of the side of the square: "))
  
# taking the input for the color
col = input("Enter the color name or hex value of color(# RRGGBB): ")
  
# set the fillcolor
t.fillcolor(col)
  
# start the filling color
t.begin_fill()
  
# drawing the square of side s
