How to revert back to python 2.7?

Whenever I ran python --version the result was 2.7 and 3.8 for python3 --version. I wanted to get 3.8 by running only python --version instead of python3 --version and after looking for the same on stackoverflow I did this

sudo rm /usr/bin/python

sudo ln -s /usr/bin/python3 /usr/bin/python

and while it did what I wanted but now a lot of things are going haywire. Therefore, I want my system to go back to the way it was before.

P.S. I wanted python to call python3 in the first place because whenever I would run mkvirtualenv name it would give me a warning that I am using python 2.7 and should switch to 3.8 but python 3.8 was already there on my computer and I thought maybe by doing the above mentioned I would get rid of the warning.

sudo rm /usr/bin/python
sudo ln -s /usr/bin/python2 /usr/bin/python
