Or on the Web server and serving information back to the browser.

Just some basic stuff that we should probably cover before we get into the nitty gritty Sze.

So with that, I'm start with a blank screen here.

I guess it conserve is just kind of a reminder of the Web development basics.

But anyways, package May we're also gonna import a couple things.

One is the just the format and then also net slash h t t p.

Then we're gonna have funk, uh, index underscore Handler and in the parameters here it's W.

And then that's a http dot response writer.

And then we had our for the request, which is a point through to http dot request uh, and now we can begin the function and let's just do format Don't f printout using the writer, uh and then hey there for now and then finally weakened due are Funk Main Empty Farms and http dot handle funk handle.

Let's try our best not to type out swear words and, uh, index handler and then finally age to be.

You can also, if you had like https, for example, you could listen to serve tea.

L s, um, not really gonna cover that now, but that just letting you know that exists.

Uh, 40,000 and then obviously you would serve on a different port.

But anyway, back to what we were doing past Mill, go and say that and let's make sure that runs a CZ.

Uh, what did hope this comma that's gonna keep getting me some python you got?

You know, you'd have to put in that calm.

I'm probably gonna python Forget comments.

Expecting it's not jumping out at me with this issue.

Would be index handler past W response writer, huh?

The index handler http don't listen and served 48,000.

If I would have read the air and full, I would have seen that immediately.

So obviously we generally like that's just plain text, like, review.

Um, usually in hte e mail, we have things called tags.

Um, just by writing them in if we wanted.

So let's just do a header one, for example.

And then I'm just gonna restart the server real quick.

And then if we refreshed source, we see us, the tags actually came through and all that s so then we could add, like, a few more things like, let's just say maybe two more lines make this may be a paragraph tag, and then we'll make this one a paragraph tie, and then we can say goes fast and simple so and then we can refresh our server.

So control c and then just up a roto Rhea, we run it basically.

And then as you can see, we got that on separate lines and all that.

Uh, the other thing I want to show really briefly is Let's just make another line.

Like we could say, um, you percent s even add percent s comma, and then we can put in what we wanna have there so we could say can And and then we can also say, What did I do here?

Okay, so it has been strong and then passed variables.

So you can even add variables like this using the percent esos good.

We shouldn't have to hit, allow every time fresh, pull it over.

The next thing I want to show, though, is if we were to view the source here, everything's on just like one line, which I mean, it's Brian at the end of the world, but, um, in general way would like this to be organized like you would expect, Especially when things start getting like if you were gonna actually coda Web site doing this.

You probably moved to using templates, which will show at a later time.

Um, but if you were doing it this way, it would be very hard for you to debug your own website.

Especially if you've got issues like you forgot to close the tag somewhere.

It's really hard to find it, and it's gonna be equally it's hard to find it if, uh if it looks like that.

So, um so the other thing we could do is you can actually do, like, a multi line print.

So this is true with all the prints, you don't have to use f print.

This could just be like your typical print line, for example.

Um, but what I'm gonna go ahead and do is let's say we wanted this exact same code, So format dot f f um, Let's just let us do these 1st 3 I think, um, and then you can use the little Tilly and then you can use that to make a multi line print.

So, for example, we could throw it away, don't need clothes.

We could throw in that this and we'll just go in this one just for just to show it.

So we'll save that and then already started server.

There it goes, Refresh and basically kind of the same thing.

And if we were to go view the source, you'd see well, it's almost good enough, but not quite so the issue is the tabbing is at least yet, like in the start.

It's not going to be tabbed weird, but then down here, in theory, these tabs or part of the multi line.

So it's thinking you want those tabs so you could get rid of them just by removing the taps butting.

And that's pride, not which you would want either.

And so again, I'll just kind of let you know that it does exist, that there are gonna be html templates.

And like I said, we can look into those, um, later on for solving this sort of a problem.

But again, we could be a source refresh, and there we go.

We fix that problem, but it is kind of you could in theory, do quite a bit of programming and make even some slightly complicated Web sites just by passing variables just like we've done here and using all the information that we've learned up to this point, we could actually make a but decent recite, to be honest.

But in general, I think you'll find that using templates will be a little easier.

But anyways, um, I think that's all I want really show right now, as far as like just adding one later.
