Create a python file called vector.py and complete the exercise below: 

# In this exercise you will use what you have learned to implement a Vector # class and a complex number class. # Write definitions for a class called Vector: 'class Vector(object):' # Your definition should include a constructor, __str__, values for the x and y # coordinates, and methods for addition and subtraction of vectors, scalar multiplication, # length, and comparison. # Write definitions for a class called MyComplex that is derived from your # Vector class: 'class MyComplex(Vector):' our definition should include methods for multiplying two # complex numbers and computing the complex conjugate as well as an updated # definition of __str__.
