Simple Python Turtle Graphic and Code: Stylized Window
A stylized drawing of a simple window with gradient-colored frame. The Python Turtle code was made less complicated and shorter by drawing the window panes as color-filled squares in the end. The Python code in this case allows the user to change the window dimensions and colors.
Feel free to copy the basic Python Turtle code that is given below. Don't hesitate to ask questions about the code if you have any. Enjoy! Please comment, like, or subscribe :)
Incidentally, for manually colorable graphics and variations, please visit my author url at https://www.amazon.com/author/basicpy...
