In this tutorial, you'll learn how to create managed attributes in your classes using Python's property(). Managed attributes are attributes that have function-like behavior, which allows for performing actions during the attribute access and update.
defvarnames(func):"""Return tuple of positional and keywrord argument names for a function, method, class or callable. In case of a class, its ``__init__`` method is considered. For methods the ``self`` parameter is not included. ...
