Updating python

[flyingscorpio]

Maybe a bit late for a response here but I found that updating Python is never clear because 1. different versions can exist on the same computer and 2. the system is dependent on particular versions on python.
This means that setting python to run python3.8 instead of 2.7 will break parts of the system.
Use aliases instead : 

Code:

echo "alias python='python3.8'" >> ~/.bash_aliases
