Dictionary comprehension the python language introduced a new syntax for dictionary comprehensions in version 2.7, similar in form to list comprehensions but which generate python dicts instead of lists. In mathematical terms, an associative array is a function with finite domain A small phone book as a hash table in computer science, 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 [3] 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 can be. E.g., graphs in excess of 10 million nodes and 100 million edges
In mathematics and in computer programming, a variadic function is a function of indefinite arity, i.e., one which accepts a variable number of arguments Support for variadic functions differs widely among programming languages.
