I used bash. And I didint do any setup for that. I have simply followed the instructions from the website posted installing Python using brew. The initial problem was probably due to my old Python instllation that was causing the problems. The paths are as described:
/usr/local/bin /usr/bin:/bin /usr/sbin /sbinI have now sucesfully installed the Python as I mentioned above, I am just not certain regarding the version. It seems that brew installed version 3.9.5 but when I check with python3 --version it still returns 3.8.2. Can someone clarify to me again what could be the problem here exactly ?
