    Methods on objects are functions attached to the object's class; the syntax instance. method (argument) is, for normal methods and functions, syntactic sugar for Class. method (instance, argument). Python methods have an explicit self parameter to access instance data, in contrast to the implicit self (or this) in some other object-oriented ...

    Python sets are very much like mathematical sets, and support operations like set intersection and union. Python also features a frozenset class for immutable sets, see Collection types. Dictionaries (class dict) are mutable mappings tying keys and corresponding values. Python has special syntax to create dictionaries ({key: value})

    Some programming languages such as Ada, C++, Clojure, [citation needed] Common Lisp, [9] Fortran 90, [10] Python, Ruby, Tcl, and Windows PowerShell [citation needed] allow for a default argument to be explicitly or implicitly given in a subroutine's declaration.

    Manipulation of these parameters can be done by using the routines in the standard library header < stdarg. h >. In C++, the return type can also follow the parameter list, which is referred to as a trailing return type. The difference is only syntactic; in either case, the resulting signature is identical:
