00:00Welcome back!

00:05In this lecture, we will see the expression and statement

00:09because this is a very basic concept

00:12where the evaluation of Python starts. However,

00:15in the last lecture, we have learned

00:18which way we can assign a value

00:21a is equal to 10, right?

00:24Basically, what do I do?

00:27I will take a memory

00:31and take a name

00:34and take a name.

00:35Make sense?

00:36Do you understand?

00:37You understand?

00:381 number is 10.

00:39I will take a name

00:41and take a name

00:42and take a name

00:43and take a name.

00:44When I have 10 number

00:47to access my name

00:49then I will take a name

00:51and return.

00:53Make sense?

00:54In this case, Python

00:58in this case,

00:59multiple variables

01:01now

01:02you can declare

01:04one line

01:05and declare

01:07one line

01:08and declare

01:09a, b

01:1010, 20

01:11and normally

01:1210

01:13will be a

01:14and 20

01:15will be b

01:16I will say

01:17here

01:18I will say

01:19I will say

01:20I will say

01:21a statement

01:22and run

01:2310, 20

01:24Basically,

01:25I will say

01:26two values

01:27in one line

01:28and add

01:29one line

01:30which is statement

01:31makes sense?

01:32It is statement

01:33which is statement

01:34which is statement

01:35which is statement

01:37so

01:38in one statement

01:39I will say

01:40two values

01:41and two variables

01:42assigned

01:43which is statement

01:44however

01:46if I

01:4720

01:48divided

01:49by two

01:50or

01:51let's say

01:52three

01:53just to differentiate

01:54now

01:55I will run

01:56now

01:57its value

01:58change

01:59this

02:00statement

02:01is

02:02this

02:03statement

02:04is

02:05however

02:06this output

02:07is

02:08expression

02:09makes sense

02:10expression

02:11now

02:12expression

02:13will give you

02:14value

02:15output

02:16and the statement

02:17is total

02:18and the statement

02:19is

02:20that

02:21it is

02:22equal to

02:23assignment
