Draw Rectangles

A rectangle we'll define as a 2-dimensional shape with a number of rows and columns. If we were to draw a rectangle made of [] with 3 rows and 7 columns, it would look like this:

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

Write a program draw_rectangles.py that has the user enter a width and a height for a rectangle. Those values should be sent to a function rexy(width, height) that uses nested loops to display a rectangle of the appropriate size on the screen.
