On some systems I find that python is not a defined command, but python3 is. Since Python 2 is no longer supported, and will hopefully become scarcer in dependencies, we can assume that python represents the latest installed Python.
Assuming python3 is defined, we can define our alias in a permanent way by:
- Open config:
vim ~/.bashrc - Add the line
alias python='python3' - Save and exit (
:wq) - Run
. ~/.bashrcfrom home.
