__bool__ | If an object has a __bool__ method, the value that this method returns determines if an object is considered to be True or False when evaluated in a boolean context. |
__builtins__ | contains built-in functions, exceptions and other objects. |
__call__ | An object that implements __call__ becomes a callable object. |
