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.

# Number formatter

For the final example, we will look at a simple number formatter. We want a formatter that can convert a floating-point number to a string, with a fixed number of decimal places. 

## Using a class

We could do this with a simple class, as shown below. The `Format()` class can be used to create a format object (as with the three digit case on line 10), or you can create and call the object in one statement (as with the five digit case shown on line 13):
