Hmm I ran /usr/local/bin/python3 and Terminal seems to be expecting something from me (the normal commands like "which python3" don't work anymore)? Sorry, I tried to find a Terminal tutorial but haven't found one that's helpful but not too difficult yet...How do I return to the normal Luos-Air:~ luoxiaoran$ and how do I edit my profile and remove that file from my PATH without deleting the python framework again?

Luos-Air:~ luoxiaoran$ /usr/local/bin/python3

Python 3.8.1 (v3.8.1:1b293b6006, Dec 18 2019, 14:08:53)

[Clang 6.0 (clang-600.0.57)] on darwin

Type "help", "copyright", "credits" or "license" for more information.

>>> help

Type help() for interactive help, or help(object) for help about object.

>>> which python3

File "<stdin>", line 1

which python3

SyntaxError: invalid syntax

This is not Apple Python (/usr/bin/python3) or Homebrew Python
(/usr/local/bin/python3). Looks like you have a third version of Python
installed.

Run /usr/local/bin/python3 explicitly rather than just "python3". Or
edit your profile (maybe ~/.bashrc or ~/.zshrc) and remove
/Library/Frameworks/Python.framework/Versions/3.8/bin from your PATH.

You an install whatever Homebrew packages you like; they won't affect
your Modeller installation.
