 So one of the things that are pretty much the reason why we like to use say python is it has this Standard library and just like your traditional library It allows you to pretty much go to a specific section and in that section I go and get a book and in that book I go and get a page and I can start to narrow things down to just Small little pieces that I want because again, you know, why reinvent the wheel in fact, you know If we think about that, you know, why do we reinvent the wheel for a lot of things math for example? Yes programming is applied mathematics, but I don't want to have to do all that math all over again So how do I do that? Well, what I can do is I can implement The math library now to do that I have to come in and one of the first things I have to do is I have to in this case import math What that does is it basically goes into the library of Python and it grabs hold of the math Library and now I have access to all these other things Utilizing the dot notation the same thing I used with format dot format math dot pie Look at that. I don't even have to type it out anymore. It already exists inside of Python for me I just have to import math Well, the same kind of thing can come into play suddenly if we kind of remember Some of our geometry for a second if we remember geometry Here's a little circle If I'm right here, that's kind of classified as a zero, but right about here that's known as Pi square If I want to convert that into degrees if we kind of look at kind of my poorly made circle That's about 90 degrees, right? I want to see that I want to actually take sort of that equation. So I can go math dot degrees And it's gonna say alright. I'm expecting something from you and I'm going to type in math dot Pi divided by You can see that that's going to then when I hit enter Give me 90 degrees and as you can probably guess if I were to follow sort of the same Structure, I can come in here. That's pie So if I were to get rid of that Dividing by two instead of 90 degrees. I've gone from zero degrees to 180 degrees or I guess that way since I'm on the camera You see I have a few of these one of the really nice ones that we have is this idea of math dot s q r t Because as you can guess that allows me to do something like the square root of 25 or Now I don't have to play the guessing game a square root of 24
