Skip the :meth:`__str__` ======================== The ``JSONSerializable`` class implements a default ``__str__`` method if a sub-class doesn't already define this method. This method will format the dataclass instance as a prettified JSON string, for example whenever ``str(obj)`` or ``print(obj)`` is called. If you want to opt out of this default ``__str__`` method, you can pass ``str=False`` as shown below: .. code:: python3 from dataclasses import dataclass from dataclass_wizard import JSONSerializable @dataclass class MyClass(JSONSerializable, str=False): my_str: str = 'hello world' my_int: int = 2 c = MyClass() print(c) # prints the same as `repr(c)`: # MyClass(my_str='hello world', my_int=2)
