Quite like every primary language, sea contains a number of key words that are reserved by the language
itself or its own operations.
Those key words cannot be used for any other purpose other than what the Python designers have used
them and defined them for.
To, for example, you can't take a reserved keyword and use it to declare a variable or to create a
class or a function.
If you do, you'll get an error message from the Python interpreter.
First, have a look at some examples of good here.
And I have a secret set that I'm using the Sony version of the Python language.
You can see I'm using version three point seven of C Python here.
And it also appears down here in the shell of brought up in the browser in one of the tabs, this file
here, which is one of the library files it will be using in a later part of this course.
And you can see that some of the words that appear in the code are highlighted based on the theme that
I've selected.
Those letters appear bold, kind of, I guess, reddish type of color.
And these are indicated as language or python reserved keywords.
Other words, such as time, for example, are also important words.
In this case, time is the name of one of the modules that are used are being used in this sketch,
but not in this script.
But they're not Python reserved words.
These are words that are used by developers at a later time to create something like, in this case,
a module.
You've got some other words, such as this one here, which is simply a fireball.
In this case, it's a constant defined inside the code and there's plenty of those.
So let's have a look at some more keywords you can see here.
Class got its own color, like Dave.
You can see both of those are reserved keywords.
And Tony has got a specific way of highlighting these reserve key words in the code.
And those look different to other keywords, such as Moad, for example, which are defined by the developer
and not reserved by the language itself.
So if you're wondering which are the reserved keywords in the C language, then you need to look at
the documentation and brought up the documentation.
The relevant part here in my browser, I'm looking at Python three at the lexical analysis page.
Scroll down a little.
You'll see right here there's a list of reserved keywords or any other keywords cannot be used by anything
else.
Now, if you do use those keywords for something else, let's say, for example, let's pick the keyword
and and let's see if we can try and create a variable such as this.
Right.
If you can see that even in the show, Thawne has highlighted the keyword and as a reserved keyword.
And of course, I got an error message.
It doesn't know what I mean by this.
If I just say A equals three, on the other hand, no problem at all.
I create the variable and I assign a value to it.
All right.
So I'm going to leave it at this.
Just remember that there are particular words in Python that you cannot use for anything other than
their intended purpose by design of the language.
And those are the three key words right here.
