For example:Jul 21, 2022 · Kolade Chris. In Python, you use the double slash // operator to perform floor division. This // operator divides the first number by the second number and rounds the result down to the nearest integer (or whole number). In this article, I will show you how to use the // operator and compare it to regular division so you can see how it works. In Python, operators are special symbols, combinations of symbols, or keywords that designate some type of computation. You can combine objects and operators to build expressions that perform the actual computation. So, operators are the building blocks of expressions, which you can use to manipulate your data.Simply -> is introduced to get developers to optionally specify the return type of the function.
