Issue

A Python script is stored in User python library directory stored in ECU-TEST. 

...

1. The script is developed for the Python version that is used by ECU-TEST.
   See: ..\ECU-TEST [VERSION]\LICENSE-NOTES\Python\PSF LICENSE AGREEMENT FOR PYTHON.txt
2. The script ideally only uses 3rd party libraries that come with ECU-TEST.
   See: ..\ECU-TEST [VERSION]\LICENSE-NOTES\Python\Included3rdPartyPythonLibs.html

3. In case the script does require libraries beyond 2., make sure to add them to ECU-TEST first
   and that they are compatible with the used Python version (see 1.)
   Have a look at our ECU-TEST help (Docs > Extensions > External Python libraries) as well.
