   "print" uses str() to represent an object. You can override str()
representation by providing __str__ or __repr__ methods in your calss. If
you provide both, you can define different representations for str() and
repr() functions. If you provide obly one, it is good idea to set other:

   __repr__ = __str__ # if you define __str__
