Description

Extend the program in the file assign05start.py by implementing the four new commands:

shapes 

Prints a descriptive list of all the shapes currently in the drawing, numbered from 1 to however many shapes are currently in the drawing, with the least-recently drawn shape as number 1 and the most-recently drawn shape as the last number

delete 

Inputs a valid shape-number (as it would be listed by the shapes command) and removes that shape from the drawing

lift 

Inputs a valid shape-number (as it would be listed by the shapes command) and raises that shape up so that it’s drawn in font of all the other shapes in the drawing
