Callable units provide a powerful programming tool Each method returns an object, allowing the calls to be chained together in a single statement without requiring variables to store the intermediate results. An object consists of state data and behavior
These compose an interface, which specifies how the object may be used In computer science, dynamic dispatch is the process of selecting which implementation of a polymorphic operation (method or function) to call at run time A method is a behavior of an object parametrized by a user.
If there are base class methods overridden by the derived class, the method actually called by such a reference or. The anonymous function accepts one argument, x, and returns the length of its argument, which is then used by the sort() method as the criteria for sorting Basic syntax of a lambda function in python is In some programming languages, function overloading or method overloading is the ability to create multiple functions of the same name with different implementations
Calls to an overloaded function will run a specific implementation of that function appropriate to the context of the call, allowing one function call to perform different tasks depending on context.
