For the "Build Tool" field, type in "/usr/local/bin/python3" for Python 3 or "/usr/bin/python" for Python 2 without the quotes and then click "Next". Choose where to save it and click "Create". In the menu bar, click "File" -> "New" -> "New File…". Select "Other" under "Mac OS X". Select "Empty" and click "Next". Navigate to the project folder (it will not work, otherwise), enter the name of the Python file (include the ".py" ...
