All language subtitles for 15. White Space

In this lecture I would like to clarify the use of white space so when to use one white space,
1

when to use more than one,
2

and when not to use whitespace, and to explain that to you I've got a script here with three parts.
3

Each of the parts will do the same thing.
4

So the first one prints out a, aa, and three a's, and then b here, and then c.
5

So the first one here I typed in one, two, three, four, five, six. Six spaces.
6

So that will work.
7

As you can see here you get the output correctly but it's not a good practice.
8

Even though that will work it's not a good practice because the code is not very readable.
9

So that's a problem with this first block.
And here in the second block
10

I fixed that so the space here is just right.
11

Basically you you want to separate things with spaces.
When it comes to operators such as the comparison
12

operators or plus or minus or a multiplication
13

the code will work even if you don't have any spaces like that.
14

However to make the code more readable it's better to have some spaces between operators as well.
15

So the space between if and a number is a must.
16

If you have that the code will not work.
17

You will get an invalid syntax.
18

However no space between operators is fine so that's the problem in this block here that you have these expression
19

without spaces, in some particular cases like sometimes I don't use spaces in the videos because I want
20

to show you the text in a greater font so I have to sacrifice with less spaces so that I can fit more
21

text in a screen.
22

So unless you have a good reason to do so please use spaces, one space, and then here that is fine.
23

So one space here, one here, and one there, and then after the colon.
24

So this is what you should know.
25

And I told you already about indentation, after a colon you all this have indentation, indentation means
26

at least one space.
27

So this would also work like that.
28

But a good practice is to have four spaces, four.
29

So that's correct.
30

And when you have more code in your script it's good to separate things with a break line, so to separate logic.
31

So if you have a conditional block there you have to write them line by line no brake lines here
32

like that.
33

That would also work.
34

But please don't use brake lights to make your code more readable however once the conditional block ends,
35

you have another logical block.
36

There's no clear cut rules here but just user logic.
37

So I thought it's good to have these print functions without brake line between them.
38

So here if I would add another function would make a brake line and then create a function here and
39

so on.
40

And of course use indentation for functions as well.
41

So after the colon always comes the indentation, an that's it more or less about spaces whitespace in
42

Python.
