 Hi again, in this lesson we're going to learn about that how to check what operating system I'm running on in Python programming language. To do that, first, what we need to do is to import platform module. Platform module in Python programming language give to us a lot of methods which provide to us further informations about our platform and our operating system. So if we want to find out informations about our operating system, we will call method system which returns the system operating system name. So it will return either Linux, Windows and so on. Let's check it, our operating system is Windows, but which version? If we want to find version of our operating system, we will use method release of platform module. This method returns the system release. Let's check it out and release of Windows is Windows 7. We can combine those two informations to be a little bit beautiful, to combine them into one string. For example, let's say platform.system plus platform.release. It will combine just those two strings. I don't want to give any blank space to those two words. And that's just a better, fancier information of our operating system and its current release. So it's Windows version 7. That's all in this lesson. Thanks for watching. See you in some next lesson. Bye-bye.
