"""Draws a (width x height) grid, with tile_function drawn on each tile.

|
|
(The draw_tile_grid function is importing from the tile.py defined functions "draw_tile_outline" and
|
|
draw_squiggle to repeat the individual elements, tiles.
|
|
Within draw_tile_grid, you use a "range" to repeat the height and width for size and moving (fly) without
|
|
drawing. Then using the definition of "return_to_x_origin" and "return_to_y_origin" to the next x and y
|
|
coordinates to position the pen to draw the next tile or begin the next row.
|
|
Just as important is "drawtiles.py" file that calls the arguments/parameters for user input of width,
|
|
height, and size. Although, the if else statement is using the defintion "draw_tile" where the argument prompt
|
|
is coming from the "tile.py" definition "draw_tile.
|
|
The 3 python files, drawtiles.py, tile.py, and tile_grid.py are drawing functions from each file without
|
|
having to repeat the code in each file. Complicated and intricate. It's functional.)
