####python 3x ##

1:Adjust the code in draw.py by adding the Rectangle, Triangle, and Square classes using the inheritance r/ship.

2:Make a drawing that uses the above added classes in makeDrawing.py.

draw.py code is given below or u can find it in this link http://pasted.co/c6f51cc6

###python 3 code## draw.py code is given in this link http://pasted.co/c6f5 1cc6. 1:Adjust the code and implement the Rectangle, Triangle, and Square classes. using the INHERITANCE HIERACHY relationship. 2: In makeDrawing.py, make a drawing that uses your classes. Please comment on the changes, thanks
