What is a good way to implement release numbering for PyCharm project?

I am using GitHub for source code control. I would like to implement numbering of the application versions. So, the first version could be 1.1.12, the second release would be 1.1.13 but I would need to deploy to Production only version 1.1.27. I need an ability to place an application version on a QA server for testing, making sure that the QA version looks exactly the way the future Production will look like.
