Now, the reason why this doesn't work is because we configured all these URLs only in our app, we also still need to configure it in our main project for Django to know what we're doing. So we can also do something like making this more usable. So now when we run this server, we can come right here. So I hope this you understood what we did in this check view is pretty basic, pretty simple stuff. So when the user name equals to this user name, the email equals to this email and the password, I just picked one from this one of these two passwords, since they are the same thing.

And then we can scroll all the way up, I will look for where we see installed apps right here. Let's go into URLs, we need to have a new view for getting all the messages. And I'm going to walk you through everything in this tutorial. So I say okay, let's go to the home page. So let's work with this one page, download. And then we see in Nigeria, n as index numbers zero. And then I'm not gonna touch the index, HTML, will not call me on it, refresh. Now we can see if a is equals to true, that means if A is true, then we can just simply say, A is true. Now we already have Django installed right here. Now if I run this, you see it gives me New Zealand, if I see minus two minus two is obviously Australia. So now we want to filter with all the list of the data we have here. Backend Developer Intern, Ecowiser | Python.org Tomi has created many popular courses both on his own channel and the freeCodeCamp channel. So you can say d f, let's just do a simple function, which is going to greet the user. So in pop, we're going to say list dot pop just like pop out to remove something. So just going to copy all the values in this too, and then paste it in history, I was referring to this theory, I run it, we have exactly the same thing we get when we print listen to this exactly the same thing.
