You can specify a function name in the block, but that function must be in scope when the .bd file is executed. You can do this with a MAIN block that references a Python program that defines or imports the functions that you need. This is a bit complex and not as well documented as it should be. There are examples of how this works here and useful detail in the README.md file.

Yeap, I already checked that, and somehow I managed it.

I edited functions.py like below.

# file location like XX.py
py_md = "/xx/xx/XX.py"
fn_name = "private_func"
# OR
py_md = "numpy.linalg"
fn_name= "pinv"

split_point = py_md.split('.')
if split_point[-1] == "py":
    split_slash = py_md.split('/')
    module_name = split_slash[-1].split('.')
    spec = importlib.util.spec_from_file_location(module_name[0], py_md)
    module = importlib.util.module_from_spec(spec)
    spec.loader.exec_module(module)
    class_ = getattr(module, cls_name, None)()
    func = getattr(class_, method, None)
else:
    module = importlib.import_module(py_md)
    class_ = getattr(module, cls_name, None)()
    func = getattr(class_, method, None)
