In shape$\_$echo$($arg$1,$ arg$2,$ arg$3)$

$($spec continues on next page$)$

shapes.py write a series of functions, each of which builds a data structure

of some sort; we've drawn the picture for each data structure below. Some of

the functions take one or more parameters; in that case, drop the values into

the data structure at the proper location. You should not do anything to these

parameters $($other than putting them in the proper locations$)$; you know nothing

about what they contain.

NOTE: All of the rectangles in these pictures represent Python lists $($that is$,$

arrays$).$ Do not attempt to use tuples, classes, or any other type.

NOTE: Notice that some of these functions take parameters. Those that take

parameters will put those parameters at specific locations within the shape that

you must generate.
