You don't need this source code unless you want to modify the package. If you just want to use the Stripe Python bindings, you should run:
pip install --index-url https://code.stripe.com --upgrade stripe
easy_install --index-url https://code.stripe.com --upgrade stripe
See www.pip-installer.org/en/latest/index.html for instructions on installing pip. If you are on a system with easy_install but not pip, you can use easy_install instead. If you're not using virtualenv, you may have to prefix those commands with sudo. You can learn more about virtualenv at www.virtualenv.org/
To install from source, run:
python setup.py install
