Draw a grid

Part 1

Using the turtle library, draw a square where each side is 20 pixels long. Use a for loop to avoid code repetition. Each iteration of the for loop should draw one side of the square.

Part 2

Using nested loops, draw 3 squares in a row side by side. Then, draw 3 rows of three squares to make a grid. Pay attention to proper indentation. You can use the function calls speed(0) to speed up the drawing, or delay(0) to go even faster for testing.

Extra

• If you used for loops, recreate your program using while loops, and vice versa.
• Ask the user for the number of rows and columns the grid should have and draw accordingly
• Currently, many edges are being traced more than once. Implement a more efficient way to draw the grid.
