The video tutorial explains two special methods in Python: __str__ and __repr__. These methods, known as magic methods, allow objects to be represented as strings. The __str__ method is used to provide a user-friendly string representation of an object, while the __repr__ method aims to provide an unambiguous string that can recreate the object. The tutorial demonstrates how to implement these methods in a Python class, using a 'Person' object as an example. It highlights the importance of these methods in making objects more informative and useful for both users and programmers.
