“import Quartz” or “import CoreGraphics”

There are currently two sets of bindings for the CoreGraphics API of macOS

• “import CoreGraphics”

  Apple ships a module named CoreGraphics that provides bindings for a large subset of the CoreGraphics API. These bindings provide a fairly Object-Oriented API, but are only available when you use Apple distribution of Python (“/usr/bin/python”)

• “import Quartz”

  PyObjC also provides bindings to the CoreGraphics frameworks, and does this through the “Quartz” package. This binds almost all of CoreGraphics (and the rest of Quartz), but does only provide a classic function-based API.

  The PyObjC bindings are available for all Python versions and macOS releases supported by PyObjC.
