I have Ubuntu 18.04 and I upgraded the python version from 3.6 to 3.8. However the python version it installed was 3.8.0 and I want 3.8.3.

$ sudo python3 --version
Python 3.8.0

How do I upgrade to 3.8.3?

You can use the deadsnakes PPA to install it. The latest version for 18.04 is currently 3.8.3-1+bionic1.

sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt-get update
sudo apt-get install python3.8

However, you should make sure that python3 points to the system version of Python (i.e. 3.6), since different versions are not alternatives on Ubuntu, and that can break your system (examples 1, 2, 3). You'll need to use python3.8 to run Python 3.8 in the future.

as the manual says, compile from source , since deb packaging is a bit behind actual releases
