  Using the Native API for Python

  Learn to use the Native API for Python in InterSystems IRIS® data platform to directly access globals, the underlying data structure, and to call ObjectScript methods and routines.

  Note:

  Python is only available on InterSystems IRIS v2019.2+.

  Create a connection to your instance	2:15	connection = irisnative.createConnection(<ip address>, <port>, <namespace>, <username>, <password>) iris_native = irisnative.createIris(connection)
  Set and get the value of a global node using the Native API for Python	2:44	iris_native.set(2, "^product", "Apple") apple_price = iris_native.get("^product", "Apple")
  Set and get the value of a global node using ObjectScript	2:59	set ^product("Apple") = 2 set apple_price = $get(^product("Apple"))
