__str__()

The __str__() dunder method returns a reader-friendly string representation of a class object. It can be called with the built-in str() and print() functions. Unlike __repr__(), it is not necessary that __str__() return a valid Python expression.

class ClassName:
  def __str__(self):

The __str__() method accepts no parameters. self is an implicit reference to the instance of ClassName.

The example below showcases various ways the __str__() can be called using an object literal, the built-in str() function, and the __str__() dunder method. All return the same string output; the aim is to make the output readable:
