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.

# Groups of built-in functions 

Python includes a number of functions that operate on iterables. We can split these into four groups. 

## Primitive functions 

The `iter` and `next` functions perform primitive operations on iterables/iterators. We covered these earlier in this chapter. 

## Creation/conversion functions
 
We have seen earlier that the `list` and `tuple` functions can be used to realize a lazy iterable into a concrete sequence. These functions, along with `str`, are also used to create and convert other items.
 
The `list` function can be used to create a list from various values, as shown below.
