 Hi again, in this lesson, we're going to talk about sale method in Python programming language. Sale method return selling value of a number, and that means the smallest integer number not less than that number. In order to use sale function, we need to import mat module, and then we're going to call sale method of our mat module, and as an argument, we could put any number. For example, we're going to put number 3.43, and we're going to get result 4. Also you can use negative numbers, and let's use this method with few more examples. For example, let's find sale of those numbers, and as you can see, this method returns the smallest integer number not less than that number. That's all in this lesson, thanks for watching, bye-bye.
