Handle confusion on choosing which python in mac

There is already a python in xcode, but it is not included in $PATH.

In short, u choose the one(s) that are installed on homebrew.

then when it comes to confusing which pip you use, just use the project based, the .venv one.

if you use the python plugin on vscode, it provides the initialization.

or initialize it using bash.

python3 -m venv .venv

then you can execute the .venv activation

source .venv/bin/activate 
# or
.venv\Scripts\activate.bat  

then install import you would like.

then deactivate when you are done.

deactivate

also keep in mind that if you use python3, then u use pip3 as well.
