Scheme was introduced to the academic world via a series of papers. Steele and Gerald Jay Sussman in the 1970s. The term list comprehension originates from two features: 1) the list-like syntax used to write such a comprehension, and 2) the fact that the output of a list comprehension is always in the form of a Python list. It is one of the two main dialects of Lisp and supports a number of programming paradigms however it is best known for its support of functional programming. List comp r ehensions are a syntactic form in Python allowing the programmer to loop over and transform an iterable in one line. Refer to the below articles to get detailed information about List Comprehension. Scheme is a multi- paradigm programming language. Unlike Sets, a list doesn’t need a built-in function for the creation of a list. Lists in Python can be created by just placing the sequence inside the square brackets. Note- Lists are a useful tool for preserving a sequence of data and further iterating over it. Each element in the list has its definite place in the list, which allows duplicating of elements in the list, with each element having its own distinct place and credibility. The elements in a list are indexed according to a definite sequence and the indexing of a list is done with 0 being the first index. List in Python are ordered and have a definite count. Lists are mutable, and hence, they can be altered even after their creation. A single list may contain DataTypes like Integers, Strings, as well as Objects. Lists need not be homogeneous always which makes it the most powerful tool in Python. Lists are just like dynamically sized arrays, declared in other languages (vector in C++ and ArrayList in Java).

A formal language consists of: a set of symbols rules for forming term rules for transforming terms to terms.
