Homebrew's Python3 framework
/usr/local/Cellar/python3/3.3.0/Frameworks/Python.framework
Distribute and Pip have been installed. To update them
pip3 install --upgrade distribute
pip3 install --upgrade pip
To symlink "Idle 3" and the "Python Launcher 3" to ~/Applications
`brew linkapps`
You can install Python packages with
`pip3 install <your_favorite_package>`
They will install into the site-package directory
/usr/local/lib/python3.3/site-packages
Executable python scripts will be put in:
/usr/local/share/python3
so you may want to put "/usr/local/share/python3" in your PATH, too.

インストールが完了したら、システムPATH
変数を更新し、次の行を~/.bash_profile
export PATH=/usr/local/bin:/usr/local/sbin:~/bin:$PATH
その後:
$ source ~/.bash_profile
Python を起動します。
