   Functional programming is a programming paradigm in which code is structured primarily in the form of functions. The origins of this programming style arise from a branch of mathematics known as lambda calculus, which is the study of functions and their mathematical properties. In contrast to the popular object-oriented and procedural approaches, f...

   In object-oriented programming (OOP), you structure your code based on the concept of objects. In commonly used OOP languages (such as Java or C#), we create a template for an object using the keyword class, and we instantiate an object by using the keyword new. These objects contain fields that store data and methods that manipulate data. In this ...

   Before we learn of the advantages functional programming offers, we must first discuss the differences between an imperative paradigm and a declarative paradigm. Imperative programmingsolves a problem by describing the step-by-step solution. Imperative programming is concerned with “how to solve a problem.” In contrast, declarative programmingrelie...

   As we said in the introduction to this article, the central concept in functional programming is that of a function; however, there are requirements that a function must adhere to when writing one. The first of these requirements is the function must be deterministic. That is, for any given input, the function must return the same output when provi...

   To execute a section of code repeatedly, object-oriented programmers use a while loop or a for loop. Loops do not adhere to the functional programming style because they maintain an external counter which is altered from inside the loop (side effect!). In functional programming, we use recursionto execute code repeatedly. Recursive functions are ty...

   In traditional OOP, you can pass objects as arguments to a function. In functional programming, you can pass functions as arguments to other functions. This is known as treating functions as first-class citizens, a term you may often see in industry. Let’s take a look at an example: This code defines a times3() function that multiplies the result o...

   In summary, functional programming is a powerful paradigm that confers many advantages. In this paradigm, we structure solutions in the form of functions. Functional programming differs from object-oriented programming. It follows a declarative style as opposed to an imperative style leading to code that is shorter, easier to test, less prone to bu...

   What is functional programming?

   • In functional programming, a program consists entirely of evaluation of pure functions. Computation proceeds by nested or composed function calls, without changes to state or mutable data. The functional paradigm is popular because it offers several advantages over other programming paradigms. Functional code is:

   What is functional programming in Python?

   • Functional programming typically plays a fairly small role in Python code. But it’s good to be familiar with it. At a minimum, you’ll probably encounter it from time to time when reading code written by others. You may even find situations where it’s advantageous to use Python’s functional programming capabilities in your own code.

   Is Python a functional language?

   • Some of Python's features were influenced by Haskell, a purely functional programming language. To get a better appreciation of what a functional language is, let's look at features in Haskell that can be seen as desirable, functional traits: Pure Functions - do not have side effects, that is, they do not change the state of the program.
