Welcome to the brand new section where we're going
to take a look at functions and I guarantee you
that no course on programming
will be complete without talking about functions. OK.
Functions are extremely important and believe it or not,
we've actually been working with some functions and we've
even created some of our own functions already.
In this course,
you just don't know it yet. So in this section,
we're going to focus on functions.
I'm going to show you how you can create your own custom functions
and then how you can use something known as the parameters.
What do we want our function to work with? What kinds of data types, right?
Things like that.
We're also going to take a look at keyword arguments,
local and global variables and so much more.
And just like with the previous sections,
there's going to be a coding exercise at the end of the section.
So please do attempt it.
Hopefully you'll be able to pass.
If not, don't worry, I'm going to provide you with this solution.
So without wasting any more time,
let's begin talking about functions.
