The functional programming paradigm can be a powerful tool, especially as it can be integrated seamlessly with procedural and object-oriented code in Python. 

In this course, you’ll learn what functional programming is, how it’s used, and the features of Python that support it. To start, you’ll learn how functions act as objects, the role of mutability, and how to perform recursion. 

In the latter half of the course, you’ll focus on closures, iterables & iterators, generators, and more. Throughout the course will be three exams which will test your understanding and really drive home what you’ve learned.  

By the end, you’ll have a new programming paradigm to add under your belt and have the confidence to start using functional programming in your own projects.

# `reversed` function
`reversed` is a useful function. It returns an iterator that reverses the order of the elements in the original sequence. For example: 

a = [2, 4, 6, 8] 
r = reversed(a) 
print(list(r)) 


Here, `r` is an iterator that accesses the elements of `a` in reverse order. When we create a list from `r`, it contains `[8, 6, 4, 2]`.

> Note that `reversed` doesn’t work with all types of iterables. It only works on sequences (lists, tuples, strings, etc). You can’t do the following:
