functional programming refers to this highly abstract programming paradigm.The 1.map () function receives two parameters, one is a function, the other is a sequence, and the map functions the incoming function to each element of the sequence sequentially and returns the result as a new list.2.reduce functions a function in a sequence [X1, x2, x3 ...] , the funct

This article describes how to use Python for basic functional programming. in addition to object-oriented programming, Python can also perform simple functional programming without relying on external variables, this article describes some of the basics. For more information

see the advantages of using adorners now, but if we want to add more than one print function, and besides add/multiply we have minus/divide and other functions, This time the power of the adorner is reflected, we can only modify a code, so that not only improve the readability of the program, but also for the future we refactor the code to save a lot of work. def decorator (F): def new_function (x, y): print ("Input:", x, y) return F (x, y) return new_ Function@decoratordef

F # is Microsoft. NET development platform of a programming language, its biggest feature is the introduction of functional programming (fp,functionalprogramming); F # is also excellent at supporting Object-oriented (OOP) programming, using the F # language, Developers have the freedom to choose

Web programming is functional programming Everyone who has long programmed for both worlds, that is he has developed local applications and programmed for web, will tell you that web programming is very different from classical application development. and it's not just the program
