I know there are other posts here asking how to install python 3.6, but all I want is a version of python 3. The repos seem to have python 3.4, which is fine but the problem is that apt-get is not responding in a way that makes sense. When I try the command apt-get install python3 I get the response:
python3 is already the newest version.
This is despite the fact that python -V command tells me python is 2.7.9. How do I install python 3 please?
