 So what if we wanted to do this exercise? I want to get the grade of a student and I want to spit out the letter, you know, what they what they're getting for the semester. So, you know, we're all kind of like oh well, you know, if I get something like an 89.79, they round up and give me a lovely, lovely, a no, we're whole or we're heartless machines. But as you kind of saw, I accidentally jumped forward. I'm able to do something called nesting. I'm able to do this idea of something known as nesting and if statement. And all it is is, just like before we were talking about that fork in the road, I can have something happen when it's true, I can have something happen when it's false. All I can do is I can actually take and put more forks in the road along the way. And that's exactly what we start to see as we expand on it all of a sudden. So it's kind of see that in practice for a second. So I take this and let's say, for example, I make a letter variable. Now you see what I'm doing here is I'm making something I call a blank string. blank string, basically stating that there's nothing in here. I'm just creating it. I know I'm going to be using it later. I want to just go ahead and use it, you know, build it now. You see, I'm also giving it that blank string. It's not there's no space in there. That's literally two quotes. It is a word with zero letters inside it. Okay, well, I'm going to say my grade is equal to we'll go 93. Now I want to test things very small, very small. So I only want to work off of this first if thing I only want to see if I'm getting my a. So if grade is greater than or equal to 90, my letter is going to equal a. All right, fair enough. Now, I'm immediately just going to focus on just that print letter. A few things you're seeing here, you notice I made my tabs to show that letter belongs only do this statement, this a statement, if it is 90 or greater, only do this statement, if it's otherwise, but I'm still able to move on with the rest of my code. I'm still able to do stuff afterwards. So I come in here and even though this is pretty harsh, I got 93. So when I run this, I should see my a. All right, excellent. So now let's all of a sudden say, well, let's test it on an 83. Now I know in real kind of grading scale, that would be a B, but in our grading scale, where I only have two letters gives you an F. So what do I do? Well, I'm going to get rid of this F for a second. And like I said, I can put if statements inside of if statements, I'm inside the else portion of my conditional statement, but I can come in and put an if there, not not going to complain if grade greater than or equal to 80. And the same practice comes in, notice it tabbed it in. So it's not just one tab over. It's two tabs over letter equals B. It's showing it that this should only occur if this statement is true, which that only gets to occur if this occurs, meaning if this is a false statement. I still like to do my testing constantly, constantly. Boom, I get my B finally. I can then come in and I can change that. Maybe we go instead from 83 to 73. Boom, I get the African. Well, now here's the come, you know, super fancy, fun stuff. All I'm going to do is use some keyboard magic. I'm going to come in here. I'm going to highlight this if conditional statement and keyboard magic. So you literally can see I'm not doing anything crazy. Control C. Control C. Control V. I paste it. Now that didn't do much for me from the get go. It just kind of pasted over itself. But if I take that same if statement, or I'm in that else block, boom, now I'm not good just yet. No, I know that looks fancy, but I'm not good just yet because this is out of indentation order. This is out of indentation order. This is out of indentation order. So I have to clean it up. I have to come in after I've pasted it. Tab, tab, tab. If I don't do that, it just all goes wrong. But I can fix this up. So that becomes now my 70. That becomes my C. I can check. Boom, C. I do that same statement one more time. Control V. I got to fix my tabs so that they belong where they are. I can check it. That gives me my D. Check my 63. I run it. Boom, there's my D. I change it to a 53. Boom, there's my F.
