This function is only used during type checking or auto-completion.

Parameters

  • python (str | None) – Full path string (file-system specific) that points to a Python binary inside a virtualenv that should be used (in VENV/bin folder). Should be absolute path (so usually start with “/” or “X:/” depending on the filesystem/os used).

  • python_callable (Callable | None) – Function to decorate

  • multiple_outputs (bool | None) – If set to True, the decorated function’s return value will be unrolled to multiple XCom values. Dict will unroll to XCom values with its keys as XCom keys. Defaults to False.
