[Language skills Python] Expressions vs Statements [Tutorial]

PROFESSOR: Let's learn
another important key term.

Well, two for that matter.

One is expressions and the
other one is statements.

You're going to hear this a lot
when talking to programmers.

So what do they mean?

Let's have a look.

If we create a piece of code
here, let's just say IQ is 100,

IQ has lowered.

And then let's say user age is
going to equal IQ divided by 5.

An expression is this
part of the code.

It's a piece of code
that produces a value.

In our case, this
produces a value.

Because 100 divided by
5 is going to equal 20.

So this is an expression.

A statement, on
the other hand, is

an entire line of code,
not this entire thing,

but an entire line of code that
performs some sort of action.

In this case, what
action are we performing?

Well, the action is that we're
calculating 100 divided by 5

and then assigning that value
to the variable-- user age.

So this is an expression.

This is a statement.

And also this is
another statement.

So if you hear me
mentioning these terms

throughout the course,
hopefully, now you

know what they mean.

I'll see you in the next one.

Bye-bye.
