After very few issues only I moved my application from Python2 to Python3 making sure it will still run with Python 2.7, and hence has python >= 2.7 as dependency only.
This was mainly done because Python3, and some dependencies are not installed in a default 12.04 LTS, and I do not want my users to have to install all Python3 only to run my script.
When I create an appname.desktop launcher I now need to decide if it starts my application using Python2, or Python3 like
EXEC=python /path/app.py
EXEC=python3 /path/app.py
But what I would like it to do is to
- Launch the application with the Python3 interpreter if Python3 is installed.
- Otherwise use Python2 if Python3 is not installed.
How can this be done? Do I need to tell it in my package installation script, or can I have a launcher which can handle both (in case people install Python3 after they had installed my script)?
