Python on Ubuntu

Python 3.8 on Ubuntu 18.04 (LTS)​

Python3.8 is not available on Ubuntu's default repos. We can use deadsnakes PPA to get it.

$ sudo apt update
$ sudo apt install software-properties-common
$ sudo add-apt-repository ppa:deadsnakes/ppa
$ sudo apt install python3.8

Note: tried this on Ubuntu 16.04 and had to add

sudo apt update

after adding the ppa:deadsnakes/ppa and before calling sudo apt install python3.8.

Confirm. Check all your python versions with ls /usr/bin/python*. You should now see /usr/bin/python3.8 there.

Make default python version​

You can add an alias as the last line of your .bashrc file:

nano ~/.bashrc

add the line

alias python='/usr/bin/python3.8'

Miniconda on Ubuntu​

wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
chmod +x Miniconda3-latest-Linux-x86_64.sh
./Miniconda3-latest-Linux-x86_64.sh

Agree to the licence agreement, answer the follow up questions (where should it install, do you want to run conda init).
