Detailed explanation-1: -Functional Programming is used in situations where we have to perform lots of different operations on the same set of data. Lisp is used for artificial intelligence applications like Machine learning, language processing, Modeling of speech and vision, etc.

Detailed explanation-2: -In functional programming, functions are treated as first-class citizens, meaning that they can be bound to names (including local identifiers), passed as arguments, and returned from other functions, just as any other data type can.

Detailed explanation-3: -In different programming languages, a function may be called a routine, subprogram, subroutine, method, or procedure.

Detailed explanation-4: -These three functions, which provide a functional programming style within the object-oriented python language, are the map(), filter(), and reduce() functions. Not only can these functions be used individually, but they can also be combined to provide even more utility.
