Quark's Outlines: Python Special Method Names
The article explains Python special method names, which allow classes to emulate built-in types by defining methods with double underscores, such as __add__ or __getitem__. These methods are automatically invoked by Python when corresponding operators or built-in functions are used. The article provides examples of how special methods enable custom behavior for objects in expressions and syntax.
- ▪Python special method names are used to emulate built-in types and are surrounded by double underscores.
- ▪When built-in syntax like + or [] is used, Python automatically calls the corresponding special method such as __add__ or __getitem__.
- ▪Special methods allow custom behavior for objects, such as defining how they respond to len(), printing, or arithmetic operations.
- ▪The article demonstrates how defining __str__ in a class controls how an object is displayed when printed.
- ▪These methods are not meant to be called directly but are triggered automatically by Python syntax.
