Sep 9, 2024 · What is a functional program in Python? A functional program in Python emphasizes the use of functions and avoids changing states or mutable data. It treats computation as the evaluation of mathematical functions and avoids side effects.
In this quiz, you'll test your understanding of functional programming in Python. You'll revisit concepts such as functions being first-class citizens in Python, the use of the lambda keyword, and the implementation of functional code using map (), filter (), and reduce ().
Functional programming is a programming paradigm that focuses on writing functions that perform tasks, rather than on state changes and control flow. Functional programming is often considered an alternative to imperative programming, which involves manipulating the state of a program directly.
Functional programming decomposes a problem into a set of functions. Ideally, functions only take inputs and produce outputs, and don’t have any internal state that affects the output produced for a given input.
In contrast to the popular object-oriented and procedural approaches, functional programming offers a different way of thinking when solving a problem. Let’s explore how to program solutions in a functional style using Python.
Learn how to approach functional programming in Python. You'll cover what functional programming is, how you can use immutable data structures to represent your data, as well as how to use filter(), map(), and reduce().
