How to completely uninstall python 2.7.13 on Ubuntu 16.04

How I do:

# Remove python2
sudo apt purge -y python2.7-minimal

# You already have Python3 but 
# dont care about the version 
sudo ln -s /usr/bin/python3 /usr/bin/python

# Same for pip
sudo apt install -y python3-pip
sudo ln -s /usr/bin/pip3 /usr/bin/pip

# Confirm the new version of Python: 3
python --version

caution : It is not recommended to remove the default Python from Ubuntu, it may cause GDM(Graphical Display Manager, that provide graphical login capabilities) failed.

To completely uninstall Python2.x.x and everything depends on it. use this command:

sudo apt purge python2.x-minimal

As there are still a lot of packages that depend on Python2.x.x. So you should have a close look at the packages that apt wants to remove before you let it proceed.

Thanks, I hope it will be helpful for you.
