Draw Boxes

A box we'll define as a 2-dimensional shape with an equal number of rows and columns. If we were to draw a box of size 3, we could make a box of little [] blocks.

[][][]
[][][]
[][][]

A box of 5 units would consist of 5 rows and columns of [] units, and so on.

Write a program draw_boxes.py that has the user enter a size for a box, n. That value should be sent to a function boxy(n) that uses nested loops to display a box of the appropriate size on the screen.

Sample interaction:

Enter a box size (1-10): 4
