who installed python 3 we should replace python to python3

If you don't want to you python2 (or not inside a virtual env), you can change you bashrc file making a alias so python = python 3. This works for linux based systems.

Place this into ~/.bashrc or ~/.bash_aliases file
alias python=python3
After adding the above in the file, run source ~/.bashrc or source ~/.bash_aliases.

It's actually python only. On windows python on CLI works as python but on Mac and Linux it is installed as python3.
