Teampy only requires that you have Python 3.x installed. Make sure that you let the installer add the Python command line tools to your path, so that you can later execute the pip command and the other commands that Teampy comes with.
After Python is installed, you can install Teampy via pip on the command line:
pip install teampy
To upgrade, use:
pip install --upgrade teampy
Pip will install several command line tools. If your command line does not recognize the pip command, make sure the Python installer added them to the path.
