I’m using a project which is expecting Python3. How can use that without messing anything up?

Question

I'm using a project which is calling a script where python means python3. However python -V shows version 2. I know I have both versions (python3 -V, shows expected version) installed.

How can I run a script from this project and it run the correct version of Python? I suspect I shouldn't have to change anything like aliases or environment paths. Although I haven't used them before, this sounds exactly like what a virtual env is for. Am I correct?

ETA:

I'm calling a script from the command line:

make foobar

Set your desired Python version on the IDE and create a virtualenv if especiall the project requires certain packages/libraries to keep it isolated and not run into certain errors down the road.
