Question

How to initialize a screen to a given size
How to use an image as your background
How to move the turtle to a given (x, y) position without drawing a line on the screen
How to draw a circle, how to draw a square (we covered some of this in class)
How to draw filled-in shapes with begin_fill()
How to clear the screen after drawing

In Python, the center of the screen is at (0, 0) by default.

Your program should do the following:

Draw a square with a length of 80. The center of your square should be at (0, 0). Use any color you want; in the example screen captures here, I’m using blue.
Draw an inscribed circle in the square that was drawn in step 1. Use a different color for your circle. I used magenta but pick any color you like – other than what you used for your square. Due to the way Turtle draws lines and circles, you’ll likely need to experiment with your starting coordinates for your circle draw.
Prompt the user for a new (x, y) coordinate for the square, and a new (x, y) coordinate for the circle.
“Move” the shapes to their new positions by erasing the original square and circle, and drawing them in the location specified by the user. The redrawn shapes should be solid-filled with the color of your choice (the shapes’ center-points are specified by the information input by the user).

Define any functions you need to make this all work. The “app window” is screen capture I saved to a png file, so your drawings might be a pixel or two shifted. That’s okay as long as the placement and movement seem reasonable from the (0, 0) origin you start at.

You can assume the user gives you “good data”: values all within the Turtle coordinate system between 200 and -200.

Notes:

Consider the given .png image of the application window is 970x635 pixels, and that should be the starting size of your Turtle screen.
If you don’t remember your geometry, an inscribed circle looks like this, and the diameter is equal to the length of the square’s side.

Tips:

It’s very difficult to test graphics-related functions without explicit test tools (screen-grabbers, functional test tools, etc.), so your most important job is to ensure your turtle movement and drawing is as consistent as possible. Of note, when you move the turtle, it has a directional heading (N/S/E/W). Take care to set the heading consistently to ensure repeatable drawing of the shapes.
You can trust the user to give you good information, and to stay within the ±200 (the default bounds of the drawing canvas coordinates)

All programmers need to be able to get the hang of a new library or learn someone else's code. With this last HW2 problem, we'll get some
practice with that -- with a Python graphics library called Turtle.
Use the Python Turtle library to render the supplied background image that looks a bit like an application window. Read up on the Turtle
documentation in the Programming in Context textbook (starting around chapter 1.5, and it's scattered throughout a few other chapters as well).
You can also check out the Python documentation e. Here are a few things you might want to look up:
