How to put python3.4-3.5 on ubuntu14.04?

Question

ubuntu

Installed clean ubuntu 14.04 on the server. It appears to have 2nd branch python preinstalled (command in python -V gives python 2.7.6). I want to use python 3.4 or 3.5 together with flask, nginx and gunicorn / uwsgi, while at the request of python -V the third version of python is displayed, flask is set exactly under the third version and the python file.py command executes the file file.py using syntax 3 - her version.

How can I build this? (preferably without virtualenv)

Answer 1

Python 3.4 should already be pre-installed in ubuntu 14.04, only it's not called python, but python3. You can check with .
You can specify it in your scripts
or make yourself an alias, like this:
alias python=python3
