I was having difficulties upgrading python3 which I downloaded from python.com. Anytime I try upgrading it, the new version doesn't show up on the terminal, so I remember going by what someone had posted on this platform about alias =... something I can't remember.
Now the problem is that, when I type python on my terminal, it shows the current version (3.10.4) of python while when I type python3, it shows the default version (3.8.8) on my terminal.
