Answer 1

Just taking the needed part from @George Oyosa's answer

update-alternatives --install /usr/bin/python python /usr/bin/python3.8 2

Just execute it and the the command update-alternatives will handle the rest for you.

Answer 2

Here is a link that may help . Check it out: Basically:

1. Check your existing python version by running:

   python -V

   or

   python --version

2. List all the available items by running:

   ls /usr/bin/python

3. Now, set your version priorities by issuing the following commands:

   update-alternatives --install /usr/bin/python python /usr/bin/python2.7 1

   update-alternatives --install /usr/bin/python python /usr/bin/python3.8 2

4. You can then list the python priorities by:

   update-alternatives --config python

5. Finally, check your default python version to confirm by repeating the first step!
