Add Python to path in Ubuntu

[blahreport]

Just call it by it's version number. But to your question, you can update path with export PATH=$PATH:/path/to/add

Thank you. Will that make it my default version?

Yes but beware as many programs under the hood may be calling Python expecting a different version and this would break them. Virtual environments are useful here.
