Using Python to open Explorer at specified path

I don’t know if this is possible via Dynamo. I’m wirting a file to a specific path and want to launch a Windows Explorer window at this path to make it easy for the user to grab the output. This seems possible via Python (see this link for an example) but I keep getting the error “No module named subprocess”, which means it’s not importing some library/reference I suppose. Any ideas? Thanks!
