Create a python function that returns a linked list that would represent the above diagram

shape_echo(argi, arg2, arg3) arg1 arg2 arg3 In 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. shape_echo(argi, arg2, arg3) arg1 arg2 arg3 In 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.
