How to make python3 be called by python command in linux?

Question

linux

Python 3 is installed on the system and it is called by the "python3" command. How can I make it be called by the "python" command?
I know it's very easy to do, but it flew out of my head. Googled but didn't find anything.

Answer 1

ln -s /path/to/python3 /usr/bin/python

Answer 2

I know it's very easy to do, but it flew out of my head.

This is not easy to do, but very simple ... - but after that, get ready to reinstall the system in a new way.

Answer 3

eselect python list  | grep python3 | awk '{print $1}'| cut -d [ -f 2 | cut -d ] -f 1 | xargs eselect python set

Answer 4

alias python3='python'

Answer 5

1. Option for the current session for the current user: 2. Option (1) plus adding .bashrc to the configuration (so as not to enter every time after login). You need to relogin at the end:
alias python='python3'

cd ~
echo alias python=\'python3\' >> .bashrc
logout

3. Option to make a python command for all users of the machine (you need rights, or ask the admin):
sudo ln -s /usr/bin/python3 /usr/bin/python
