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().What...
Functional programming (FP) is a paradigm in where a program is composed of functions. A function is a building block that encapsulates a computation. A function applied with a value, always returns the same computed value. FP avoids mutating state. FP a
In this course, you'll 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().

Python内建了map()和reduce()函数。 map()函数接收两个参数,一个是函数,一个是Iterable,map将传入的函数依次作用到序列的每个元素,并把结果作为新的Iterator返回。 reduce()函数的用法是把一个函数作用在一个序列[x1, x2, x3, ...]上,这个函数必须接收两个参数,reduce把结果继续和序列的下一个元素做累积计...
Functional programming is not something that needs to be fully used or not used at all in Python. It can be considered to be something akin to a “style” of programming. Its principles can be used with other paradigms based on the problems that need to be solved. At the end of the ...
Python - Functional programming Functional programming is a programming paradigm in which most of the work in a program is done using pure functions. A pure function is a function without any side effects; its return value is always determined by its input arguments, so it always returns the ...
In Python, functions are first-class objects. They can be passed as arguments to other functions and a new functions can be returned from a function call.6.2.1. Example: Tracing Function Calls For example, consider the following fib function. def fib(n): if n is 0 or n is 1: ...
As you work your way through this series of articles, we will explore together some motivations, idioms, techniques, and patterns from the functional programming world, and apply them in Python. Not because we should, or want to, but because we can. And hopefully we’ll all learn something...
