How to set Python3.5.2 as default Python version on CentOS?

Question

Is there a way to set the Python 3.5.2 as the default Python version on CentOS 7? currently, I have Python 2.7 installed as default and Python 3.5.2 installed separately.

Answer 1

If this

sudo ln -fs /usr/bin/python3.5 /usr/bin/python

doesn't work (it should)

you could just add an alias into your /home/.bashrcwith this command:

alias python="/usr/bin/python3.5"

and if this does not work either you should just use virtual env. Read this page to get started.
