Switch easily between Python versions on a Mac using pyenv

Install Pyenv:

brew install pyenv

Configure Pyenv in your shell:

# Add this to your ~/.zshrc or ~/.bash_profile
export PYENV_ROOT="$HOME/.pyenv"
command -v pyenv > /dev/null || export PATH="$PYENV_ROOT/bin:$PATH"
eval "$(pyenv init ~)"

source ~/.zshrc
OR
source ~/.bash_profile

Use pyenv:

# List available Python versions
pyenv install --list

# Install a specific version
pyenv install 3.11.5
pyenv install 3.12.0

# List installed versions
pyenv versions

# Set global Python version
pyenv global 3.11.5

# Set local Python version for current directory
pyenv local 3.12.0

# Check current version
python --version
