discussion of a “require” library probably isn’t necessary.  It’s pretty straightforward to include the logic using existing methods.

For the version of python, test against sys.version_info
For the modules, put your import calls in a try block and handle exceptions
For the OS version, test against os.name or sys.platform
The last one, “functionality,” is a bit vague.  Probably another candidate for a try block.
