You have added the PPAs which are not supported for your Ubuntu release.
So you need to remove this PPAs first:

sudo apt-get install ppa-purge
sudo ppa-purge ppa:jonathonf/python-3.6
sudo ppa-purge ppa:deadsnakes/ppa
sudo add-apt-repository -r ppa:tista/adapta

then update package lists and install updates with:

sudo apt-get update
sudo apt-get dist-upgrade

and you are done.

Please note that your system already have Python2 and Python3 installed. They are available as python2 and python3.

Documentation (man-pages) for commands used:

• apt-get
• ppa-purge
• add-apt-repository

Have you visited Jonathon's Overview page on Launchpad?

He clearly states that the PPD you are attempting to access is not public. Have you made a donation toward his efforts?

That is probably not your main issue. I believe you already have Python3 installed.

Let's get to the real issues here.

Ubuntu 18.04 comes with Python 3.6 installed. Which version have you installed on your system?

Try this in a Terminal window:

$ which python3

$ python3 --version

Those two commands will tell you if you have python3 installed or not, where it is located, and which version you have installed.

If you have the full updated Ubuntu 18.04 installed you should have Python3, version 3.6.9.

WARNING: I suggest that as a beginner to python you do not use PPAs.

Hope this helps!
