PYTHONPATH environment variable not saving on macOS

Question

Running echo $PYTHONPATH returns a blank line:

freddy@dave ~ % echo $PYTHONPATH

freddy@dave ~ %

echo $PATH returns properly

freddy@dave ~ % echo $PATH
/opt/homebrew/bin:/opt/homebrew/sbin: ...

.bash_profile for user freddy:

# Fig pre block. Keep at the top of this file.
export PATH="${PATH}:${HOME}/.local/bin"
eval "$(fig init bash pre)"

# Use Python 3.10, not homebrew
export PYTHONPATH="/Library/Frameworks/Python.framework/Versions/3.10/bin/python3.10"

export PATH="/opt/homebrew/bin:${PATH}"
source ~/.bash_profile

# Fig post block. Keep at the bottom of this file.
eval "$(fig init bash post)"%

Why does echo $PYTHONPATH return nothing? And how do I assign it to my Python3.10 path?

I've tried restarting, this does not help
I've run source ~/.bash_profile (this just closes the terminal after execution though?)
A test variable: export TEST="TEST" also echos a blank line

As the comment suggests, I'm trying to use Python3.10 instead of my Homebrew installation, which is for some system packages

"(this just closes the terminal after execution though?)" - Do you have an exit in .bash_profile? - Then remove it. — koyaanisqatsi

There is no exit. the entire file is shown above. Should i remove the source ~/.bash_profile from under PATH in the bash_profile? — Freddy Mcloughlan

I am using zsh, not bash.

I moved PYTHONPATH to .zshrc and it saves as an environment variable now.

However, I have opted for the pyenv setup. And have added the following to my .zshrc file:

eval "$(pyenv init --path)"
