Integration with OMNET++

[ana-luisa00]

While trying to integrate OMNET++ the script tells me that I do not have Python installed and to install it, however it is installed on my machine as you can see below

Any idea of why this might be happening?

I have limited experience with using Omnet++ but from what I can figure is that the script is looking for python without the 3. To check this you can type in python, which will probably lead to an error.
A simple solution would be to set an alias but there are different solutions, which you can find here https://askubuntu.com/questions/320996/how-to-make-python-program-command-execute-python-3
