#  In python classes data attributes (data fields) are created
#  with assignment statements like
#          self.data_field_name  = ...

#  The word 'self' is commonly used to refer to 'this' instance object.

#  The data attributes of the Rectangle class are created when
#  the initialize_rectangle() method is called.
