keep getting this error when I run my python 2.7 code to find and connect with my port which I have a gps tracker connected ... I'm using 2.7 ... I figured once I get this working I can translate it into python3..
this is the error .. as I try is tell my laptop what port my GPS trackers in connected to

Nothing to do with the question. Norie should get full points.
If you want to have code, that runs with python2 and python3, you could install the future package and call program futurize to translate your python file to a version, that executes with python2 and python3 (but it requires the package future installed for execution).
Sometimes the result of futurize is not correct, but it does a rather good job.
