Some languages, such as Perl, LISP, JavaScript and Python, make the stack operations push and pop available on their standard list/array types. Some languages, notably those in the Forth family (including PostScript ), are designed around language-defined stacks that are directly visible to and manipulated by the programmer.
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})
In computing, a hash table is a data structure that implements an associative array, also called a dictionary or simply map; an associative array is an abstract data type that maps keys to values. [2] A hash table uses a hash function to compute an index, also called a hash code, into an array of buckets or slots, from which the desired value ...
To emphasize the effect of a statement, a comment is often used showing the top of the stack before and after the statement. This is known as the stack effect diagram. PostScript uses separate stacks for additional purposes, including variables, dictionaries, procedures, some typical procedures, and control flow statements.

The dictionary problem is the classic problem of designing efficient data structures that implement associative arrays. [2] The two major solutions to the dictionary problem are hash tables and search trees .
It was built in pop culture. The transferability of that brand should be obvious to everyone now,” Oates said. “Not just athletes, but people in general really need to think about those ...
